M1917 Heat Stamps.....

[ffuries]

For some years now, I've been compiling a list of all the Heat Stamp numbers I can find for the M1917 helmet. So far this is what I've been able to find. I've read of a possible W second letter unknown, and a ZL and ZM, but I've yet to see an example of those three. I also don't know of there are additional Z ones. Every so often I get bored and hit the auction sites, various militaria sites to see if I can find more.

If anyone has any examples not listed I'd be apprentice if you would let me know, or an example of the three possible ones listed.

I wasn't, but I could so that also.......

I looked at my 1917 it is a ZJ.

My 1917-A1 appears to be marked "FKS 21". I would assume then that it was not an "upgraded" 1917.

Good hunting. Zach
