Ordnance drawings for M1/M2 carbine parts wanted

Looking for copies or source of original ordnance drawings/blueprints, USGI M1 and M2 carbine parts, for research project. All steel parts. Looking specifically for metallurgical standards that were found on these drawings. Prefer e-copies, pdf files.

Thanks,

lots of luck there. the paper drawings available on ebay are copies from the RIA and include notations for "some" metal data (heat treatment, etc), are sometimes hard to read, but are generally good for what the set contains. however, the publication is not inclusive of all parts of the carbine. included are bolts, firing pins, etc. barrels, sears, triggers, etc are excluded research is hard because humpers with machine tools are on the loose.
