I inherited a mauser 19101914 from my mother. It says Waffenfabrik mauser A-G oberndorfan on the barrel. On the other side it says Mauser-6.35. The serial number is 261388. My gun smith says it needs a fireing pin type 1 with integral guide pin and a trigger sear. Can any one help me with parts and/or a gunsmith who can get this little gun working again?
