(OP)
These materials were spec'd for building the Browning 1919A4 machine gun. Mil-spec was QQ-S-624. Any leads on where to find info on this mil-spec also appreciated.

you will likely find that several of the materials are no longer used.
I'm not sure where to find old military materials spec. you might try a military history group or an office like that in the defense dept.
