Been watching for one for a while now, and stumbled onto one at gunshow today- cheap!
Pretty good shape- bore was left dirty, and has some light rust.
It is soaking overnight (Kroil) right now, and will get a good scrubbing tomorrow!
I disassembled this one to check the lock and clean the set triggers, and found an orange tag with a 5 digit number on it under the rear of the trigger guard placed there by the factory I guess. The number does not match the serial number on the barrel.
I've never noticed that on others I have taken apart before.
Any ideas?
