14032140331403414035Had this for a while and don't even remember where I got it, but have always wondered if it is a rare prototype or someones repro fantasy piece. Anyone ever seen one marked like this before?

It is heavy and well made, but.................

Thanks.

It is a converted M7 grenade launcher note the original markings were ground off.
