Korean War era and later carbine upgrades and rebuilds.

TM 9-1276/TO 39A-5AD-2, February 1953 listed five standing work orders that applied to Carbine configuration:

* MWO ORD B28-W3 ... Replacement of leaf type rear sight with adjustable rear sight.
* MWO ORD B28-W4 ... Replacement of magazine catch and plunger to provide increased holding.
* MWO ORD B28-W5 ... Replacement of front band to provide for attachment of bayonet.
* MWO ORD B28-W6 ... Replacement of sliding type safety with rotary type.
* MWO ORD B28-W7 ... Replacement of disconnector plunger assembly to prevent its loss (M2 carbine only).

These work orders were implemented by CONUS Arsenals/Depots, Overseas Depots or Field Maintenance Units on in-service carbines as needed.

Carbines rebuilt at CONUS Depots were stamped with the rebuild facility initials on the left side of the stock. Carbines rebuilt at overseas Depots were not marked.

I think this is a fine list you have here! However, I think some of these MWO`s were actually applied during the latter part of WW2 and before the Korean War.

Thank you. Yes they were -- as you point out -- it was an ongoing program. The information I relate here is from the 1953 Tech Order.

The first carbine I carried (December 1950) had undoubtedly been through the rebuild program before the Korean war started.
