Check out the bottom left 45 Auto case. Just “45” no maker or AUTO. The “45” is identical to that on the REM-UMC (1952-1960), first style R - P (1960-?), and PETERS 45 AUTO headstamps. By visual ident the primer is Remington too. No ejector scratches to indicate its ever been chambered. The jacketed wadcutter bullet isn’t like any I’ve encountered, and certainly unlike any of the Remington wadcutters which have a dimple at their top. Any thoughts?
