I just recently acquired this 1915 Gewehr. As it is my first Gewehr, I am looking for any information that can be provided. The rifle has matching SN with the exception of the bolt and butt plate. The rear of the stock has been repaired so the butt plate may have been replaced at the time of the repair. Stock is marked with same number as other parts so I would guess that it is original/ Unit disk is marked with what I believe to be 68.R.11.11 with a proof mark. I am interested in any history that may be attributed to this unit. I am also interested in all of the other markings on the metal and wood. I have tried to research them but have not found much (unlike markings on my Enfields). Maybe I am just looking in the wrong places. Thanks for looking. Would love to hear from other forum members.
