I just picked up a blued 6" model 19-4 that is nib, it is a 200 year City of Los Angeles commerative 1781-1981. It has a LAPD shield on the right side of frame with "City of Los Angeles 200th anniversary 1781-1981" on the right side of the barrel. It came with a wooden presentation box. Does anyone have an idea as to the value and how many were made?
