I recently bought a LeMat (Pietta Cavalry) off an NSSA member and it arrived without the shotgun ramrod and the cylinder release tab was fused to the frame. I let it sit for days covered in Liquid Wrench and tried everything I could to pry it loose, but I could see it was rusted to the frame. Also the grips did not match and one of them was very proud of the frame, looked quite bad while the other side was fitted flawlessly.
I got a refund from him (minus $50 he decided to keep for unknown reasons) and have since lost interest. It was a gorgeous piece... just so far beyond any other Pietta in terms of fit and finish (minus one of the grip panels)... will have to pick one up someday for sure, but I want the Navy model that has an improved hammer system and cylinder release mechanism.
