Mike,I have 2 of these tools and they are the best!I highly suggest all of you grab one. It has a regular drum key, slotted drum key, screwdriver, wing nut tightener and 7/16 wrench for consolette bolts. A must for any vintage drummer, I say.
got one recently myself aaron. they are worth it just for the wing nut portion alone! these were actually pretty uncommon. but the guy on ebay seems to have a deep stash of nos models.
