"Mil-J-8279G AMENDMENT-1",Just a total guess, military airforce.
I'm sure someone who actually knows will tell us.
"Mil-J-8279G AMENDMENT-1",
I just checked online and it says:It’s not that, because MA-1 appears on the spec label in 1954, when the spec was simply MIL-J-8279.
I suspect it doesn’t stand for anything as such and was just some internal specification, to differentiate it from other items in the inventory. There was probably a reason MA-1 was settled on from a specification listing perspective, in the same way they went with A-2, B-3, B-15, L-2, K-1 etc in relation to other garments, but the lettering doesn’t stand for anything.
Along with European military size labels, especially BelgianDamn....
Someone long gone will probably laugh for all eternity over everyone trying to figure that out.
Could it be a clothing system developed by Aero Medical Lab in the 1950s? Cause I found some other objects like MA-1 helmet and MA-1 gloves with contract no.
