I've currently got three Camco kits and have had two others previously. Camcos were made at three different locations - Oaklawn, Chanute and Los Angeles.
Collectors tend to have a real thing about the Oaklawn drums over the others but I've had kits from all locations and they're all great but the Oaklawns have that more classic 60s sound. The LAs were the classic 70s studio drum and you'll hear them on more records from that period than you'll realise. Notable for having considerably under-sized shells which gave the toms an almost timpani-like quality.
Camco were always the smallest of the US manufacturers and, despite having been responsible for some genuine innovations, they never really cracked the lucrative rock market (but the jazzers loved 'em) and couldn't withstand the Japanese influx with their superior stands and fittings for much lower prices (the problem for all the US manufacturers at the time).
In 1978, after a few different owners, they eventually sold the toolings to the fledgling Drum Workshop (who weren't even making drums at the time) and the name and some other elements (including their pedal design) to Tama which is why you will often seen the very fine Camco by Tama bass drum pedals. Tama also had a stab at making "TAMACamco" drums which wasn't really a success despite the drums being pretty OK (though not very collectable in today's market) and they briefly had Elvin Jones as an endorser.
Camco originally came from the George Way Drum Company, George Way being one of the greatest innovators of 20th century drum manufacture (he's the guy who came up with the distinctive turret lugs amongst many other things).
Very, very early DW (up until maybe the mid-1980s) bear a slight resemblance to LA Camcos but this is long before DW became a big name in drum world so these are probably rarer than Camcos.
I'm sure others can add some stuff. Here's one of mine (an Oaklawn re-wrap).
