I have a friend with a Norwegian 1911 with a .22LR conversion where the .22LR round actually slides into a .45 cal dummy round. The weapon functions as a normal .45 cal and the .45 casings kick out with the .22LR casing, so you have to located and save them all. So it uses a .45 mag etc., but we are guessing it was made in the 20's or 30's. Anyone have any information on what this may be? We are working on getting pictures and markings.
