This articles is from 2015 but I recently just saw it thanks to an old ‘Nam vet sharing it on facebook.
The .50 caliber M2 machine gun was designed in 1918, near the end of World War I by John Browning.
Production began in 1921 and the weapon was designed so a single receiver could be turned into seven different variants by adding jackets, barrels or other components.
Roughly 94 years after the first production run of M2 machine guns came off the assembly line, the 324th weapon produced made it to Anniston Army Depot for overhaul and upgrade.

In more than 90 years of existence, the receiver with serial number 324 has never been overhauled.
“Looking at the receiver, for its age, it looks good as new and it gauges better than most of the other weapons,” said John Clark, a small arms repair leader.
Despite the fact that the weapon still meets most specifications, it may be destined for the scrap yard.
Modifications made to the weapon in the field mean part of the receiver would have to be removed through welding and replaced with new metal, a process which usually means the receiver is scrap.

Hearing about this didn’t surprise me much. I was under the impression that until recently a lot of the M2s in service were that old or close to it. I think Howard maybe mentioned to me once that he saw M2s still marked from WW2 era while he was in the Marines.
