Gentlemen,
These type files sent to Ordnance Units to change the old style to the "New Front End" This ended the Gas Trap Production of the M1 Garand. It gives us a lot of date on parts numbers and other data as well.

Some data has been posted before others have not.
Thanks again

Clancy...
Is there a date on the drawing you posted? (I did copy and expand it using PaintShop, and can find no date anywhere on the displayed document.)

Um..., er..., seems to me I've read that the hardened gas cylinder lock was adopted after it was discovered that rifle grenade firing would break (or otherwise damage) the "soft" variety. Also seems to me that the cross-slot gas cylinder lock screw was adopted relatively late, having been preceded by the single-slot screw. I'm by no means certain that the single-slot screw featured the "poppet" valve, adopted when the M7 (?) M7A1 (?) grenade launcher was adopted, but I don't think it did. Those models of grenade launcher, as I recall, came in to use very late in WWII.

Interesting that an official document would call out very early gas-trap parts replaced by relatively late gas-port parts. I wonder why?

This could be a drawing for "Field Maintenance".
That way the rifles could have the proper parts replaced and explain why the newer parts are from later WWII date.
Just my 2 cents

Gentlemen,
I have the complete set of these file updates they also have the complete set of text files which give all the dimensions of the changes as well. However, there are NO DATES ON THEM. I have a good idea of when they came out but you guys know that if I don't have an Ordnance file I will not post. This way you guys get the Orders and not what you heard at a gun show.
Thanks again
