I just picked up some unusual new 8mm Mauser rifle brass cases. The headstamp is
"G.F. 8MM". They are new boxer primed with copper colored primers with red primer sealant visible. The primers are not military crimped in. I couldn't find any references on the internet. Has anyone seen this brass before? I think it is of European origin. The Seller said it came out of the XPLO company in Plattsburgh, NY when it closed around 20 years ago. Any info would be helpful.
