I'm thinking possibly Pearl Valencia, original 3 piece from the sixties, with 13", and floor tom added later, (70s, possibly also Pearl, or stencil thereof) but I could be wrong. I'd suggest keeping wrap as is, unless really damaged, to preserve any collectability value. Maybe look into treating shells, and polish the rest. Same wrap on all drums, or is there a difference?

Thanks for the info and advice! The wraps are similar but I believe the kick/rack/snare are different than the floor tom.

Looks like the one shell pictured has been varnished already. Does the bass drum have any reinforcement , where the toms mount? The kit was originally , probably a 3 piece ( kind of odd, because the centre mount would indicate otherwise) and the bass shell might be a bit stressed , hanging two toms off of it. I have seen a lot of those bass drums cracked and wiggly on top because of too much strain on the wood, mostly due to moving the drum with the toms intact. Be very gentle with it----once that wood starts to go, it only gets worse until it has to be completely rebuilt in some way.
