I have inherited a Mauser 7.65/32 cal, model 1914, I think, pistol. Serial 275xxx. It has a clip that does not fit. It is also missing a grip screw. I would like to know where I can purchase the proper clip and a grip screw. Also how many rounds will the proper clip hold? Looking around the gun, the numbers match, the finish is at least 85-90%, inside the barrel looks good too. Wood grips are smooth-not checkered. Not interested in this gun as a shooter, after shooting a clip, but would like to have it complete with a little more info and approximate value. Thank you for your help.
