All kinds of musical instruments: brass, woodwind, accordions, percussion, electronic equipment, anything to do with making sound and other weird stuff.
This must be the shallowest snare drum ever! TWO INCH! Stamped “JOHN GREY, ENGLAND” on the snare at both ends. There are six “floating” lugs. The batter head is marked “JOHN GREY – HEADMASTER” & is an early plastic head.
