I have been trying to find info on a 1911.1911A1 that I have. One older gentleman said he had seen these years ago, but others have said it is a custom job, OK the parkerizing matches , slide says Model of 1911 US ARMY, frame says united states property with EEC, E (front of trigger gauard), and eagle head on the left, right side sr# NO1348xx and below that 1911 A1 with a 1 on the front of the trigger guard. I believe it is a Remington UMC 1911 frame but with 1911A1 modifications, But where they were done I don't know. Any help?
