A so called 'Coffin' metal logo badge as was used on the very first JTM45 Marshall amps. It is a reproduction badge from a batch cast many years ago using an original badge as a mould. So this is one of those original reproduction badges, not to be confused with the one that Marshall is now putting on its amps. It measures 3 7/8" and the holes are centred at 3 1/8" (99mm and 79mm).
