A colt official police nickle plated with no serial number on the butt but the frame and the cyl. crane has serial 565965 indicating an early 30's. Looks almost unfired with a checkered trigger and serations along the topstrap. I picked it up years ago at a Va. gun show from a dealer. It had ill fitted grips at the time indicating to me that the original grips may have been stripped off the piece. I have some other early colts and I would like to discuss colt revolvers. JJ White
