This is a 1921/1920 Police pistol I recently purchased. It has the sear safety, and part of the magazine safety. Has anyone seen any new information on the circle S as shown on this pistol? Some indicate that this is a Simson rebuild, but there are no other Simson proofs on the pistol. It has the WaA4 acceptance marks, and a Ma.422. gripstrap marking. Additionally is has 422. stamped on the back of the receiver just above the lanyard loop.
