Mickey, sounds like a Weimar Army Luger to me. 6th Division,10th Regiment??? Army and Police shared some of the same acceptance stamps. If it was not drilled for a sear safety, my guess is an Army Gun, serial range shows some in the "b" block as well. Magazine would have been tin or nickle plated sheet steel body with wood bottom (or later replacements of aluminum bottoms) Thor~~~~~
