The old vet I got the last colt from called again and I met him this a.m. This is a 1943 Colt #1.089,xxx, slide number matches the frame, colt45 auto marked on the side of the barrel just above the leg., slide stop checkered and the hammer is the short wide spur. The mag is marked C-L. Gun checked out all correct with Clawsons book. Not the cleanest '43, but better than a rebuild. He said this is the last he will let go but he still has my number.
