Dating M1 sweatbands

[christek]

Hello Gents,

I have a couple of questions regarding dating these two post WWII sweatbands. I am in the process of researching the non-dated pre Vietnam war era gear, still a bit confused on the DSA numbers. Any help with these would be much appreciated.

The first band is what I believe to be an late 1950's to early 1960's. It has some clear markings and some are a bit hard to read: 'DSA 100 47 50 0514 153 6671'

The second I have had a while - I think it came in a capac 52 liner I got a while back. The problem is the DSA number is impossible to read! The only main difference I can see is that these serial numbers faced the wearer not the shell - Is this perhaps an indication of production time? Is there a way to date post WWII bands besides the DSA number?

Many thanks for reading and any assistance!

Best regards,
Chris

to be honest the DSA/NSN/FSN is about the only way i have ever been able to date the postwar bands

I think the only way to date it would be by finding an identical sweatband with an intact DSA. You could probably do a quick search on ebay or the like.

I can't actually date this one but here is some history about DSA (now DLA) Organization History
