I picked up my newest toy Saturday. A NIB 1975 Colt GCNM. When I got it home and did a full disassembly, I found that the sear and disco had been cannibalized and replaced with a fairly beat disco and a bashed to hell sear... The sear spring was bent all crazy to keep the sear from falling off the trigger hooks. The sear has actually been peened to lengthen it!

That's what I get for buying somebody's "Safe Queen". All the externally visible surfaces and parts were immaculate. The rot was all inside. See pics.
