I've got a 12" Slingerland rack tom with a serial number of 187XXX and the Slingy black & silver badge. I believe this drum to be from the 1970-1972 time-frame. Would I be correct?
The drum's got a diamond mount on it and it certainly appears to be factory-installed. I was under the impression that by this time the company was using the Set-O-Matic mounts on its toms. Am I mistaken?
I've attached a few pics of the interior shell of the drum.
