The grip is thicker due the fact it is a standard govt issue stock which was just checkered. I'm assuming the barrel threads were for a silencer and the cover didn't show in the auction photo. The gun didn't have the Lyman 17A but I added it so I could shoot it.
The DST looks to be from a Mauser. The rifle is a M1922 still with the double firing pin and is #295.
Has anyone seen the little roller that pushes up on the striker to maintain an even engagement before?
Any guesses on who did the work?
