Also worth mentioning as part of the unique shells are the fact that the shells seem just a bit undersized and they have totally different bearing edges...
The edges aren't sharp like modern drums, but they're not quite as round as most vintage drums... They are really a perfectly "narrow oval" of sorts. This seems entirely made possible because the re-rings are ply and not solid, and thus not as chunky as Rogers/Ludwig/Slingerland...
A drum-builder/friend (who's been at it for a long time) told me, and I forget the explanation, that no one can (or does) cut edges like that anymore.
I have seen back-cut/roundover edges on some LA drums (more than one kit) that seemed original - though I can't say for sure. Definitely fatter and not as Camco-y (but still really nice!) - but I have also seen/owned LA Camcos with the traditional edge.
Camcos have always struck me as a well-built almost "modern" style drum shell (or more modern, relative to their contemporaries)... but now they've aged 30-40-50 years... If only someone would make a modern floor tom bracket that fit them!
