Hello members, very interesting information here, my friend could find a torso of a jager pistol, unfortunally there were many parts lost, the main spring,grips, screws and trigger lever, fire pin,and magazin. Is there any schemas what looks the parts like? the large screws are M4,5 metric or Withworth? Thanks for any hints and links. The serial number is 1038x, this piece lightly rusted, same serials on all parts, its proofed with NPv, 38xx.17 on slide. best regards,Andy
