In Rob Cook's "The Slingerland Book" he says "In the 1970's the drum finishes Slingerland offered were literally limitless." Then he has pictures of clear drums, denim drums and drums with Coca-Cola labels as the finish. He goes on to say, "Slingerland even offered to cover drums with artwork of the drummer's choice."

I offer this information not to say that your drums may not be a rare set but it sounds like finding matching sets for anything produced during the 70's could be challenge.

To be more specific, there is NO chrome at all on this kit. down to all the nuts and bults, rims, everything is powder coated black or something. I'm just curious if anyone has info about that. Did they do other colors? white chrome? I've seen the black chrome shells, maybe they had an all black kit?

the only different plating I'm aware of is the gold plating as in the black gold sets, maybe some owner of the set had the hardware powder coated at some point?

I remember seeing a set like yours at a local music store-once.I'd say it is quite rare.Please don't automatically equate rarity with monetary value.I never saw one of these sets on a stage anywhere,just the music store.
