It is admittedly AT MOST a Colt barrel and cylinder and a bunch of new parts, including the receiver ("lock frame.") How much is a collection of spare parts flying in loose formation worth to you?
I recall seeing a Patterson at Dixie one time. The fine print on the placard said the grip and receiver were Colt, the barrel a replacement; don't recall which the cylinder was. It looked good and would have been worth a bit of money but not as much as a complete original gun.
