    Pedersen "Selfloader" Rifle and Carbine

    (51 picture virtual tour)


    Observations and Pics: by Terry Hawker (click here)
    Terry would also like to extend a special thank you, to Keith Campbell and Dan Retting at Martin B. Retting Inc., Culver City, California, for their gracious contributions to this article.

    The Pedersen rifle was designed by John D. Pedersen, the same man responsible for the Pedersen Device that would have allowed the conversion of bolt action rifles to semi-autos. His reputation was such, that according to Julian Hatcher, John Browning himself once modestly referred to Pedersen as, "... the greatest living arms designer and probably the greatest of all time." The great man's statement would undoubtedly provoke a few skeptical questions today.

    Pedersen was a contemporary of John Garand and they both worked at the Springfield Armory during the 1920's on their separate designs for the US semi-automatic rifle trials. Although Pedersen's rifle came very close to being adopted, from the military point of view the arm had several flaws and Pedersen's contract with the US government was eventually terminated in 1930. Mc Arthur's edict in 1932, that, due to the enormous supplies in government warehouses of .30-'06 ammunition, the new semi-auto rifle would be in that caliber, became the final nail in the Pedersen's coffin, as the .276 design couldn't accommodate the longer round.

    Vickers-Armstrongs, of Crayford, Kent, England, tooled up to produce the rifle when they thought it was going to be adopted in the US, and it performed well enough in the British semi-auto trials of 1930-33 to justify the production of a sporty-looking, carbine version with a two-inch shorter, exposed barrel for the cavalry.

    Although beautifully designed and executed, the rifle had some drawbacks. It employed a Luger-like, toggle- link, hesitation blowback action that lacked a breech lock and required lubricated ammunition. Pedersen developed an invisible, dry wax process to solve the lubrication problem, but the military evaluators were not pleased. During the US trials, the few rifles made at the armory used non-reversible, 10-round clips, but by the time of the British trials, a reversible clip had been produced.

    For a detailed explanation of the principles and technical aspects of the Pedersen system, see, "Automatic Arms, Their History, Development and Use", by Melvin M. Johnson Jr. and Charles T. Haven, or the more easily found, "Hatcher's Book of the Garand", by Major General Julian S. Hatcher.

    According to the various, noted texts, and the sorely-missed former curator of the Pattern Room, Herb Woodend, serial numbers of these rifles never got much above the 200 range. Exactly how many were produced is so far unknown, but we can get a pretty good idea of the number that made it to the US.

    An advertisement from the San Francisco Gun Exchange, in an American Rifleman magazine of the late 50's, appeals to, "Advanced Military Collectors", and offers, in condition like new, Pedersen rifles for $250.00 and Pedersen carbines for $300.00. For those really advanced collectors that were a bit better heeled, both were available for $500.00! The most interesting thing about this ad is they list the serial numbers available; 17 to 208 for the rifles and 240 to 262 for the carbines.

    Then, in 1962-63, Martin B. Retting, the owner of a well-known gun store of the same name, in Culver City, California, imported the Pedersen rifles and carbines that had been kept in the Vickers Museum. Mr. Keith Campbell, who was there then, and is there still, remembers splitting the shipment with Sam Cummings, another well-known importer/dealer of the era. Interestingly enough, this shipment included some Vickers Lugers that were also in the Vickers Museum.

    According to Mr. Campbell, after the split, Rettings kept about 8-10 of the rifles and carbines. That would seem to account for the missing serial numbers 1-16 of the rifles, and a few of the carbines from the San Francisco Gun Exchange's lot, still supporting the belief that only 200-odd of these neat little semi-autos were ever made. One had the receiver cut in two, another was sectionalized, but of greater interest is Mr. Campbell's report of duplicate serial numbers observed, specifically, two serial number "1" carbines! (See "Collector's Comments and Feedback" Note #1 below)

    That would certainly complicate the task of confirming how many of these rifles and carbines were produced, but unless someone finds Vickers' production records for confirmation, we may never know. Those records might shed light on the possibility of foreign orders, rumored before, but brought to light again, when Mr. Campbell related that, at the time of the museum acquisition, he heard the unsubstantiated rumor that there were about 20,000 rifles, bound for Spain, on a ship that went down at sea. Unless those records turn up, those rumors will stay unsubstantiated.

    As can be seen from the photographs, this rifle was a joy to behold, beautifully made and superbly designed, despite its flaws. It is sleeker and more sporting-like, especially in carbine trim, than just about any military rifle, (although the Model 1896 OVS Mauser Carbine is a close second!). It is a 10-shot semi-auto in a package that compares favorably with the 1903 Springfield in size, weight and handling. Just looking at it makes one appreciate Pedersen's genius, and yet, knowing the level of machining expertise required to produce the barrel and action, and the number of milling operations demanded to manufacture the stock, one can't help but wonder, "What was he thinking?"

    Collector's Comments and Feedback:

    1. Thanks to Mr. Thomas N. Magee, some very interesting new information on the Pedersen rifles and carbines has come to light recently in a piece he wrote for the "Favorite Firearms" section of the December, 2008 issue of the NRA's, "American Rifleman", titled, "An Unusual Vickers".

    Mr. Magee reports, that in early 1966, he bought one of those Pedersen rifles that Martin B. Retting had imported from the Vickers museum and was told at the time, by Martin B. himself, "...that he had been informed by factory personnel that they had made only 13 pieces of this "Model PB."

    What makes this rifle so interesting is the fact that it is, as far as can be determined from the limited sources available at this time, a previously un-reported variant. Most other Vickers-made Pedersen rifles are "Pedersen Self-Loading Rifle, Model P.A.", as is the subject of this MKL article.

    The existence of a second model range of rifles and carbines does help explain the reports of possible duplicate serial numbers, and, with Mr. Magee's statement, "...that Retting obtained a near-mint carbine, as PB Serial No. 1., and several PAs, including serial No.243.", Keith Cambell's recollection of seeing two serial No. 1 carbines is further explained and confirmed.

    Now we need to discover how these two models differ from each other and try to confirm which came first, though logic would lead one to believe it was the PA's.

    On a technical note, Mr. Magee informs us that the twenty rifles and five carbines made in 1926, at Springfield Armory, for the U.S. Army trials, lacked the facility to eject the non-reversible clip they used when partially filled. The Vickers-produced models, however, using a re-designed magazine and reversible clip, could eject a partially filled clip, by holding the bolt open and pressing forward on the trigger.

    Many thanks to Mr. Magee for filling in more gaps in the knowledge of these fascinating rifles and carbines. .......

    4. When adoption of the Pedersen looked like a possibility for the U.S., Pedersen got Vickers to make up some with an eye to the world market. They are essentially the same as the U.S. Pedersen that lost out to the Garand rifle in U.S. trials.

    Due to the operating system of the Pedersen (a delayed blowback), the rifle couldn't handle the .30-'06 without a massive increase in weight. So Pedersen, apparently quite a salesman, persuaded Army Ordnance to adopt the .276 Pedersen, a cartridge the rifle could handle. But the Chief of Staff of the Army, one Douglas MacArthur, thinking of the billions of .30 rounds stockpiled in the event of war, turned down the idea of a new caliber, and the Pedersen faded away.

    Just to clarify a couple of points. First, the Pedersen toggle breech is often compared to that of the Luger, but the Luger is a locked breech, recoil operated system. The Pedersen is a delayed blowback, nicely engineered to give a maximum of mechanical disadvantage in the early part of the breech opening.

    Second, the Pedersen rifles made by Vickers, like the U.S. Pedersens, were chambered for the .276 Pedersen, NOT the much larger and more powerful .276 Enfield for which the Pattern 1913 rifle (click here) had been chambered. There is not much doubt that the .276 would have been a poor choice for WWII. While lethal enough, its lack of range and penetration would have meant our troops being outranged and outgunned by the Germans and even by the Japanese if they were using the 7.7.

    Here is a pic below of the cartridges being discussed. I included the .280 Ross because some publications have stated that the .276 Enfield is identical to the .280 Ross. A look at the picture will show that to be erroneous. (Like the Pedersen cartridge, there were a number of development stages for the .276 Enfield, but all were basically the same in appearance.) .......

    5. Here is a list of a dozen Vickers Pederson rifles held in the collection of the 'Explosion!' museum near Portsmouth in the UK.

    210 219
    211 221
    212 224
    213 226
    214 227
    215 228


    Supposedly, these were handed in by the wife of a deceased Royal Navy officer. A couple of them had bad cracks through the wrist, one rifle being in two pieces. There was a number of different butt lengths visible, showing a variation of about one and a half inches between the longest and the shortest.

    It's interesting to see how the numbers correlate with the rifles sold off as surplus in the States.

    The Pattern Room have a rifle s/n 24 - which bears British ordnance markings from use as a trials weapon, and a carbine s/n 245.

    The above reflect a time when Vickers was trying to drum up business between the war's, not just in the military arena but also in the sporting field, with their range of .22 target rifles, bolt action sporting rifles and shotguns; but that's another story. .......

    7. I've had three Vickers Pedersen rifles. I bought my first one from Shore Gallery Auctions in Chicago in the middle 60's. It was SN 233. In the late 60's I bought another almost mint (with a short stock) SN 166. I got another one this week from Julia's Auctions SN 187. This is the only one I have now. Sure would like to get a loading clip for it!

    In private email discussions with Terry Hawker, I indicated I didn’t think SN 166 was a carbine, as Terry seemed to think it might be. The stock had a shorter trigger pull than SN 233. All other measurements were the same, like barrel length. As I told Terry, I had a good friend who was a Canadian weapons mechanic during WW2. He told me that England made their rifles fit the rifleman. They had different length butt stocks to put on the Enfield rifles so that a more correct trigger pull could be obtained. The way that the Pedersen stock is made with the narrow comb, the stock was not cut down. It was made that way.

    8. Here are pics below of my US Pedersen clip. Viewed from the side, it is identical to the V-P non-reversible clip, but the bottom is slightly different, probably making the two non-interchangeable. ....... (Feedback by member Clem “Micoclem” Miller)

    9. When Clem mentioned he had owned three Pedersen rifles, one of which had a "short stock", I instantly, (and erroneously, as it turned out), pictured one of those beautiful little carbines, not realizing he was referring to a rifle with a short butt. My apologies for the confusion and thanks to Clem for pointing out the varying stock lengths. A line has been added to the specification section so no one else makes the same mistake. .......

    10. Six Vickers-Pedersen rifles were in the Cogswell & Harrison Ltd. inventory when it was acquired by Samuel Cummings of (then) Interarmco in 1959. Most were in the low-to-mid 200 serial range.

    Nos. 157 and 232 were in the Cummings collection. I have No. 229. These British guns are readily distinguished from the U.S. trials version by the external shape of the magazine, which is noticeably different.

    Refer to the thread in the Commercial Auction and Sale "Gossip" (click here) forum titled Reference Thread - Poulins and James Julia Auctions (Oct 3-7, 2008). A carbine, No. 257 (click here), was sold at that most recent Poulin for $8,912.50 U.S.

    No. 108 was featured many years ago in a "Rifle" magazine article. .......
