It's at the gunshop, don't know if they let me take photos. I may just buy it if the price isn't too much. The sn# apperars to be struck after the finish. I have not seen a pinned front ramp sight. The trigger and hammer are jeweled, the gap is quite narrow, and when locked up, the rear play is very minimal, and the rotation seems acceptable. I'm no expert. Maybe I should pass on this one.
