Based on all the aluminum mounts, I'd say your kit is a 1968, possibly early 1969. The aluminum Setomatic wasn't around very long. However, it's odd that it would have the newer style bass drum T rods. There's always the possibility that the torpedo rods where changed out for the newer style. Still, with Slingerland, anything is possible!-Mark
aaaah okay. that's kind of what i was figuring on the date - i found the chart last night with badges/serial number range vs date range and kind of figured they were probably late 68 early 69.
the t rods very well could have been changed - when i unpacked it all i initially thought a lot of the hardware was repro stuff due to it being so clean. then on closer inspection found little things here and there - there's a small piece of chrome missing off one of the floor tom legs and the bottom floor tom hoop, the kick hoops have obviously been touched up in a couple of spots and i think the handle on one of the t rods is slightly bent.little things like that but,overall, they have obviously been really well cared for and they sound absolutely warm and gorgeous with fresh heads.
what did surprise me was how rough cut the rerings and edges were. all my other slingerlands have been 24 inch kick,mostly mid to late 70's 5 ply drums and these look relatively primitive internally in comparison.almost like the rerings were cut with a knife or something :)
either way, it's been a few years since i've had a nice slingerland kit and i'm stoked to be back in the old drum nerd fold. thank you guys for the help!!
