Now, here's a real classic as seen in photos of 60s mixers: a vertical throw fader with semi-circular travel. Scaling is from -30 to 0 with contact switches at each end stop. The body is about 4" deep with multi-pin connector. The pins are a little tarnished and will need some contact cleaner.
I have 3 of these puppies. I can separate them or sell them as a job lot. Kinds sounds like a stereo pair with a spare. You'll need some modest carpentry skills to mount these correctly into an operating surface. Once that's done it's Thunderbirds are go!
Price? Hmmm, better call me.
