This is way out of my area!! I recently picked up a 105mm M-14. It’s old and dirty! What I can make of the headstamp is:
105 MM. M 14 TYPE 1 LOT NO. 138-23139-1 M.M.C. 1942
There is also a mark at 9:00 I can’t make out and marking on the prime I can’t read because of the dirt and corrosion.
Who made it and whats the best way to clean it up (or should
it leave it as is)?
