How is the sling loop attached to the grip frame??? Screwed, riveted, other??? Does it swivel???
Looks like it might be a Mauser holster-stock hogged out in places to accept the Artillery Luger and with Luger attaching iron...But there were prototype Luger holster-stocks (that looked different) and this could be a variation...
Interesting item, to be sure...Whatever it is...
