I have a US canteen pouch (Baker Lockwood 1941) with a lot of markings.

One marking is still a mystery to me: AL-050. Stamped on the "ear" and the bottom.
It looks like a laundry number, but it has three numbers instead of four. And two letters instead of one. What kind of number is it? I don’t think it has a connection with the rest of the markings, as the service number (3?09050?) does not correspond with the name E. GLASSER
