M2 stock ID help, please - #5 and K in a circle

[Bill Ricca]

I need more documentation to prove it, but I think it may be Keystone Manufacturing from Boston, Mass during WWII. Keystone had two other stock contracts, one which I can identify for the 03 series rifles.

Keystone had a "Stock Assemblies" contract from 10/44 thru 5/45. The time puts it in line with M2 Production. Can't prove it yet, but it makes sense.

I doubt it is post war due to the location of the markings.
