I'm looking at a hinged dark brown pebble-grained (not wood-grain) Colt Official Police box from 1950. It has the word Colt on the top in gold letters and it is cream colored inside, not green. There is no serial number anywhere on the box, although the box and label are genuine. The gold label has a black fine-line border and has "COLT" in box letters, ".38 Special", "Official Police Revolver" and "4 Inch" printed on it. Did Colt ship this style of box without the serial number marked on it? I don't have a photo to post, sorry.
