Well it has hardware matching the Hollywood Ace model, It is a Slingerland 5ply shell... And the badge appears to be 76-78.. It could be a cut down Shell from a 14" Tom... Going by Factory "P" stamp being stamped right on the edge.. (or having been partially severed in a cut down).. also do not see much of a snare bed there.. does it have one??
Cheers
John
