Lots of red flags.Keystone under the tone control as has been said is of for trans badge,not so much for 60's keystones.
Two tom mounts,one a double which isn't factory,or there wouldn't be a cymbal mounting bracket on the drum.
The second consolette rail mount should be on the side of the bass,not on top like some club dates were,so that was moved or added.It's also mounted real close to the back(possibly front) of the drum,which seem to be missing it's badge.
Those grommets on the mounted tom badges don't look original,and seem to be sticking out further that factory ones do.Those interiors should all be white resocoat,but,some lery late 60's keystones did have clear interiors.
The original hollywood twin tom kits came with two 12" toms,later on with a 12 and 13.But that kits seems to have 2-13" toms because of the large classic lugs.A 12" tom from that vintage would have small classic lugs.
I think the bass is a 22" but can't be sure.If there are 10 lugs on one side,then a 22,if 8 a 20" drum.
I'm thinking black cortex wrap.
I would have to inspect those drums up close,with a tuning key in my hand.Just too many questions,and things just not lining up.
