I remember Valley Drum, I think they were the main distributor for Blaemire's drums. They'd get the shells and put on whatever hardware you wanted, which accounts for the various kits/snares out there with typically either Rogers, Slingerland or Ludwig hardware. I forgot when they closed, I think they had a fire and that was the end of things.
As for value, hard to say. I agree that custom/"unknown" drums generally possess diminished resale value, but there may be some L.A,. guys who feel differently about those particular drums.
