Sirs,
a friend sent me these pics, is there anyone who knows what’s this?
…it looks like a double diameter case with four holes around its largest part and two crimps on its smallest diameter part…the largest cylindrical body is 14mm long and has a diameter of about 12.5mm…the smallest diameter cylinder has a lenght of about 15.4mm and a diameter of about 6.2mm…its head while larger than the head of a 6.5 Carcano cartridge looks similar.
The odd case was found by a friend in a country where there were most of the battles between the italian and austro- hungarian armies during the first world war.
All the best
Andrea
