I’ve thought for a long time that Siamese 8mm charger clips were most probably made in Japan. Not that there are overt markings that say as much, just the general way in which they are formed that share many similarities with Japanese made Arisaka chargers. The sidewall lugs have the same press tool marks as have the sidewalls themselves.
My only doubt had been that Arisaka clips have their cartridge retaining flange made as a ‘recurve’ where the side is bent down by 180 degrees before being folded outwards to form the flange. Until now the only Siamese clips I’d seen had the retaining flange simply formed by bending the sides over by 90 degrees to make a channel.
Here is a Siamese charger ( the top one in the pictures) that I’ve found that is just like an Arisaka one, only longer as you would expect from the rimmed base of the Siamese cartridge. I’ve included one of the more often seen ‘simple’ Siamese ones as well as the shorter Arisaka one.
Has anyone got packaging from Japanese made 8mm Siamese ammunition?
