Simson & Co. Suhl, Luger, 9mm, 4 inch barrel, all matching except magazine, all parts marked with the eagle over 6. Toggle axle is unmarked. This gun is truly an attic treasure. It has been sitting in its holster since it was brought back from WWII. Finish wear and pitting is caused from the holster. Holster dated 1935 cannot make out manufacture. Both gun and holster could use some TLC.
