Just newly discovered this. Am an ex-pro player now working in the music business and based in Sweden.
At one point had three Camco kits (am now down to one) when I never considered that it was collecting - but I guess that's what I was doing. Just looking to get a chrome covered brass Camco snare and then I'll be satisfied (at least that's what I say now).
But can feel with this much information at hand......well, those Gretsch round badges were always nice and for a really obscure one to get the experts scratching their heads there is always Drouyn..........
