Very cool! The color was called Lavender Satin Flame and is fairly rare. This was either the Modern Solo or New Rock Outfit. Same drums, but different hardware. Your actual drum sizes are 8x12, 9x13, 16x16, 14x22 and a 5x14 snare drum. Satin flame finishes are very prone to scratching and "spider-webbing" around the lugs. How does the finish on this kit look?
It also appears that the Setomatic is the first-generation aluminum brackets. I'd swap them out for the later chromed version, which are relatively easy to find.
As to value, if the shells, wrap and hardware (lugs, tension rods, hoops) are in good condition, I could see this easily selling for $800+. Retailers might put a price of well over $1000. As has been mentioned by others, Slingerland drums just don't seem to command what Ludwig and Rogers go for.
Overall, a nice kit in a cool and rare finish!
