After the Post WWII Overhaul/Rebuild programs, were any of the Carbines sent to Vietnam or other Foreign aid required to be 'Rebuilt Stamped' ? None I'm aware of, unless they were included with the Garands that were rebuilt in the 60's as the Vietnam War heated up. I believe most of these Garands were serviced by Tooele, Springfield, Red River and I believe Letterkenny. IIRC these were engraved on the metal or had a hang tag attached.
I'm thinking the NOP-M-6# stands for a Privately owned or Government Facility where it was used for Defense / Security.
I found a 1960 Navy Dept Identification Guide for Navy Contracting Activities Accounting from 1960. It has Contract Symbol codes and Abbreviations in it. Here is the link: https://www.google.com/books/edition/Identification_Guide_for_Navy_Contractin/DPyEX8VvYCQC?hl=en&gbpv=1&dq=1960s+Naval+Ordnance+Plant+Macon+NOP&pg=PA8&printsec=frontcover" rel="nofollow - https://www.google.com/books/edition/Identification_Guide_for_Navy_Contractin/DPyEX8VvYCQC?hl=en&gbpv=1&dq=1960%27s+Naval+Ordnance+Plant+Macon+NOP&pg=PA8&printsec=frontcover
In it I find listings for:
Naval Ordnance Plant...... Louisville, Ky. Naval Ordnance Plant...... Macon, GA. Naval Ordnance Plant...... Forest Park, ILL. Naval Ordnance Plant...... Pocatello, Idaho. Naval Ordnance Plant...... York, PA.
Assuming in the NOP-M-6# marking that the M does stand for Macon, GA... Could it have been used for security at a Facility involved in manufacturing explosives.
Here is their Insignia estimated adopted ~1960:
I earlier found a Google review of- Department of Defense Appropriations for 1960, Hearings before the 86th Congress. A very long report breaking down costs, percentages, pie charts, proposals and estimates from what was called the Norfolk Overhaul and Research Program. Mainly about needed post Korea War upgrades to the countless different facilities. Not far in to it the name was changed to Norfolk Overhaul Program, since 'The Research' had been completed. Most of the requested funding was given the green light. In the request for funding, it included costs for the extra civilian security and arms that would be required.
If NOP-M-6# has anything to due with Norfolks Overhaul Program (As far as property security) I can't explain the M.
