Here's what I got and did research to trace the serial number to the year:
Keystone badges
Bass 654868 1968
8X12 Rack Tom 402627 1966
16X16 Floor Tom 403917 1966 and stamped inside 9/27/1966
B/O pointy badges
18X16 Floor Tom 1180380 1976
9X13 Rack Tom 1749411 1979
Snare 1235912 1976
Unfortunately, the bass and 8X12 rack tom were painted black inside so I put a coat of Benjamin Moore white over it.
The snare is in terrific shape.
16X16 floor tom has white interior from factory.
9X13 rack tom is wood grain.
18X16 floor tom is Granitone
Only mod is an additional set of spurs on the bass drum.
They cleaned up nice, with not a lot of rust or pitting.
I would consider selling the snare and the 18X16 floor tom separately.
Would $2000 for all be fair?
