Thank you all for your help.
I spent last week taking them apart, cleaned all the hardware and oiled the shells. On the weekend I put them back together and have been tuning and adjusting the tom hardware.
The last owner took off the original Set O Matic, and installed a Rodgers Memrilock which is kind of beat up, but has great adjustment. I'm sure they'd look better with the original hardware.
They have these oil filled heads, awful. I need to get some new ones.
The drums are big: 22x14 BD, 13x10 & 14x10 toms, 16x16 & 18x16(!) floor toms. Loud too.
3 ply shells: maple poplar maple, maple reinforcement rings, 4 spur mounts for the bass drum though I only have 3, no wing nuts, the screw holes are stripped out, and no spurs.
I'm using C clamps with some shims on the BD rim.
I've found two mounts on ebay that I'm gonna try to snag.
I've got to find some spurs, or maybe some 3/8" rod and make them myself.
