collecting 1940 rifles

[cgroc09]

I used a later trap barrel.
The ribs were not corrected.
A direct conversion, maybe at one time but the ports were chromed on the barrel. I didn't think they did that in 1941.

I can understand your view on s/n 5777 - but there were some barrels manufactured by SA during WW2 that did have chrome plated gas ports to salvage a "undersized " or out of spec barrel. Art Tuttle wrote a short article about salvaging M1 barrels as far back as 1941. My old friend, Harold Murtz who was the Senior Staff Editor at Gun Digest had purchased an M1 rifle at Klein's Sporting Goods in Chicago in early 1964.. He never shot it as he collected Lee Enfields. In the early 90's he decided to sell off most of his collection and showed his M1 rifle to me, it was serial number 544121, all the parts such as the Type 1 lock bar, rev 12 heat lot RE5B bolt, uncut rev 3 op rod, appeared correct
except the barrel was a S-A 10-41 D35448-7 REP 33A with "chrome pads", the T.E. was just over 1.0. Harold never changed the barrel nor shot the rifle as he has little interest in M1 rifles. I believe it was a barrel salvaged in 1941 and used in later production.

Very interesting. Thanks for the information.

I still believe 5777 was done at a later date on the basis the pads were chromed and the 7th round mod. was not done. I assume if they did do a gas trap to gas port conversion , at that time , the 7th round mod. would have been performed ( possibly ).

Can someone explain the 6/40 and 7/40 barrels? The Gas Traps were not re-called to SA, as I understand it. So why the June and July barrel dates? Re-barreled at SA in the summer? But not re-called. Seems like more to the story then we know.

Some simple answers without going into a lot of detail or reading the books: Both the gas trap configuration and gas port rifles were both being produced through July 1940, hence the S-A-6-40 and S-A-7-40 dated barrels on the gas ports.

Gas trap rifles were not recalled but cycled in during rebuild

There are some excellent books available

Robert is correct, both were being assembled from about mid-June. The gas ports got the new dated barrel and the old undated gas trap barrels were being used up.
