I've had the misfortune of hearing that distinctive 'pow' a few times, and in two cases, we found original 'factory' chalk marks on the backside of the plate. Circles around pits and cracks and somebody's initials. Must a been a tolerance factor that allowed these defects to leave the plant. The chalk marks look like new, even after 60-70 years. Maybe the tuner victim can have the customer produce the removed plate in court...???
