No, I bought these from DanerousDuckStuff. They seem to specialize in vintage jewelry, clothing, ties, footwear, etc, etc. When I see something odd on a site I always check the to see if they have other, similar items. I breezed through lots of this seller's items and didn't see another piece of militaria.   I just got them today. Here is a better view. These do not react to UV light. But I see a shiny substance on the extreme edges that I suspect are to minimize fraying. 

What a great find, 10k rope is very cool, never new they made such a thing.

Well believe it or not I found an old sheath that is very close to the WW-2 version.....Close enough to where I'm fine with the fit, just not quite as narrow as the two in the pic.   I did have to make a strap/snap for it as the one on it was broken off on one side.    I bought it about a month ago with a lot of old knife scabbards a local gun shop got in.....No maker's markings I can find.    LOL....At least it has part of the guy's name and US Army scratched in it....It will serve.     

You are correct-they were brothers! https://www.findagrave.com/memorial/31709537/casper_yost-offutt Thanks for the post.       Steve

Militbuff,   In the interim, can you post pictures of the buckle disassembled from the sides?   Meaning, just a picture of the buckle and pieces lying flat?     Thanks,   OD

It is a good post war eagle complete with the matching black twill backing    -Ski

Picked up this US WWII Mapcase that was most likely reissued in Vietnam with unit marking on the flap.  Would anyone know what unit this is?  Many thanks.   Regards, Drew
