Your Thoughs on a retro "rebuild"

[Mott]

Gents,
I wanted your thoughts on a project I am thinking about. I have a CMP IBM carbine with a Saginaw barrel on it. It is standard after war rebuild with the late features. I have an interest in the IBM as I used to work there so, This idea is personal in nature. So here it is: I would like to rebuild the carbine to WWII configuration. I have an IBM stock and hand guard to replace the present stock with already. I will need a flip rear sight, front barrel band, sling, oiler, push safety, and unfortunately a flat bolt as the CMP rifle came with a round M2 bolt. I do own a copy of War Baby so I can look up codes etc. I guess my questions are.
1) First off is this a stupid idea from the start?
2) The parts seem to be available but I will probably end up with 5-6 hundred $ in parts to prepare for the retro rebuild. Is it worth the $? Original, unmessed with carbines in original config tend to run into the multi thousands so even at this price point, it is less $ for me and I could still shoot her and not feel so guilty.
3) Would I be messing with the gun too much if I ever did wish to resell (e.g. any well read person would know it was a retro rebuild as the rear sight is of course heavily staked etc.)?

I mean I would use "real" original vintage parts and make as many of the parts IBM manufacture as I could find, so the rebuild would be "correct" in that sense. If my kids ever wanted to sell the piece after I went away I could have a build sheet for them. I know there is a lot of "junk" going on with any military collectables out there. The reason for this post in the first place is I do not want to be seen as one of "them" (buggers who mess with collectables) nor do I want to mess up a nice piece of history. Thanks for your thoughts.

Sincerely,
Mott

Welcome to the forum!

Stupid idea? No. "Correcting" M1 Carbines and M1 Rifles is a popular pastime. It can be expensive and frustrating, but not stupid.

However, you have to realize three things: first of all, you are laboring under a misconception. It isn't necessarily true that "Original, unmessed with carbines in original config tend to run into the multi thousands" (by "multi thousands" I would assume you mean $2000 or more). Mint examples can certainly sell for over $2000, but others are available for under $2000:

I saw an original Underwood at a local gun show for $1100, so they are out there. You just have to be patient, save up your money, and be ready with cash when you come across one.

Second, the parts you will need ("flip rear sight, front barrel band,... push safety") are rare and expensive if you can find them. There are way more fakes, er "reproductions", than originals out there for sale, so you are likely to end up paying a lot of money for Made in China parts to put on your currently all-American IBM.

Also, you would need to find an IBM barrel to make your IBM carbine "correct". Even if you find a decent IBM barrel for a reasonable price, then you have the expense of changing the barrel. You will also have to make sure your headspace is correct.

By the way, beginning around serial number 3744xxx IBM began using round bolts, round bolts are not "M2 bolts", and a round bolt might be correct for your particular IBM. If you are going to "restore" your carbine then correct reference sources are vital if you want to do a proper job. I suggest that you join the Carbine Club, buy the back issues of the newsletter, and study newsletter #329.

Third, even if you are able to find genuine original early IBM parts to use, the final result still won't be the same or worth as much as a true original IBM carbine. A true original carbine has a patina that can't be duplicated by putting a bunch of "correct" parts together.

I think CMP carbines make great shooters and should be appreciated as such. Also, the carbine's service didn't end on September 2, 1945. Carbines that look just like yours does now served in Korea and beyond Does anybody else like late model features? - Military Surplus Collectors Forums

So, you certainly can do whatever you want with your carbine, including "correcting" it. But I think that if someone wants a World War II-style M1 Carbine they should save up their money and get the real thing, rather than "restoring" an honest post-WW II (upgraded and improved) configuration carbine. Just my opinion.

IBM didn't use the type 3 (round) bolt till late in the 3.8 to early 3.9 serial number range. The key to restoring a carbine is the dovetail for the rear sight is if it's been staked for the type 2 or 3 rear sights or not. If not staked then it would be a good one to restore. But as Milsurp stated it's expensive but can be very enjoyable.

Carbine Club newsletter #329, page 5:

"The flat bolt was used to about 3744xxx. During a transitional period, 3744xxx-3849xxx, both flat and round bolts were used. After 3849xxx, round bolts were in general use until the end of production".

The type 3 bolt didn't start into production till Feb./March 1944. During Dec. 7 through 15 1943 10 carbines were inspected then test fired for 6000 rounds. The highest serial number was 3844404.

Mine was produced in Jan 44, and has a round bolt. Here's a couple of photos. The only carbine in the collection with provenance to a WWII Lt. Col., a pilot in the Army Airforce.

I have the same feelings as you seem to have, thus my hesitation to "fix" the IBM I have and the post to the Forum. The CMP IBM carbine I have is "perfect" as it is. I too like and appreciate the late features. There is just this nagging urge, if you will, to have one that is as issued in WWII. I need to think on it some more and make a decision. I have a "few" nice CMP examples perhaps acquiring another "original" is not so bad (elbow in ribs). I mean is there really such a thing as having too many carbines? I say loudly NO!
Has anyone dealt with Mr. Hadley lately? I purchased a nice IBM from him some time ago. I am not sure he is even in business anymore.
Finally, thoughts on Riverbank Armory for parts? Reputable?

Thanks again gents!

First of all, Welcome to the group!

"Finally, thoughts on Riverbank Armory for parts? Reputable?"

Most of us here have our thoughts about George, AKA Riverbank.

May I suggest you spend some time researching the forums before spending your money there?
In the meantime, enjoy what you've got.
Just a thought.

I think if you save up your money and get a legit original World War II configuration carbine, the urge to "fix" your other carbines will miraculously dissipate and you will have a new appreciation for them.

When I decided I wanted a Kar98k, I bought a "Russian Capture" (RC) Kar98k because they were easy to buy and affordable (just like CMP carbines), and matching number or mostly matching non-Sovietized Kar98k's seemed way too expensive, hard to find, and just unobtainable (like original World War II carbines seem to be now). But I wanted my RC Kar98k to be more "correct" (German) than the Sovietized mixmaster that it was, so I did what many people do: removed the Russian shellac from the stock, and bought replacements for the locking screws and cleaning rod that the Soviets removed and melted down. I even bought an ex-Norwegian Surrender Kar98k stock that had the "correct" Waffenamt stamps for my rifle.

But with time and patience and searching I began to get matching and mostly-matching non-RC Kar98k's, and my desire to "correct" my RC Kar98k completely disappeared. I removed the cleaning rod and locking screws I had added, because it is "correct" for a Russian Capture Kar98k to not have them. I am even going to re-shellac the stock because that is the "correct" finish for a Russian Capture Kar98k. Now that I have German configuration Kar98k's, my first Kar98k will take its rightful place in my collection as an example of a Russian Capture Kar98k. If I had just been more patient and left it alone, I would have had a 100% authentic Russian Capture Kar98k and all the money I wasted on the extra stock, cleaning rod, and screws.

Russian Capture Kar98k's and mixmaster carbines: they are what they are, and can be appreciated for what they are.

I have a World War II-configuration carbine, so I have no desire to downgrade/backdate my shooter CMP carbines. They are perfect examples of Korean War carbines (and I'm currently reading a great book about the Korean War) and I even upgraded them further with Type 5 operating slides (based on a recommendation posted by Newscotlander) and round bolts. I shot three of my carbines tonight to zero the sights. With my CMP Winchester I put the first five rounds in the black at 50 yards but to the left of center. I adjusted the windage one click right and the next five shots were in the bullseye. That's what these CMP carbines are: great shooters that also have history just the way they are.



Riverbank Armory? That's exactly how you end up spending a lot of money for fake parts in my opinion. Here's some interesting reading

Cast my vote for leaving your present IBM as is. As stated above it would be difficult to match wear patterns even if you are able to find the correct USGI IBM parts. In regards to Charles Hadley, I have not had recent dealings with him but have had two carbines in the past that were described by him as completely original, only to find out later they were put-togethers with fake parts. Be careful who you deal with in regards to "original" carbines and parts. Many of us have learned our lessons the hard way.
