In the 70's there was a sliding potentiometer based on a rotary pot and a worm gear. The pich of the worm gear was such that the travel produced about 300° rotation.
The worm gear was made out pf plastic.
 
The first Studer (tube) mixer in the 50' use helical cylinder to turn a pot from linear translation

ADM (Audio Design Manufacturing) was based in the Detroit area and sold desks primarily to the TV broadcast industry.  The used their own design (patented) for the faders.  I also have a short movie clip I recorded, but .AVI files aren't allowed here.

Gotham faders and others of that vintage were designed that way IIRC.
 
Or you can over engineer it the way Shure did on their SR101 8 channel mixer.....  ;D

Auditronics Grandson consoles also have faders that work that way, can't believe I don't have a pic...
 
The Ogden made Spectra Sonics 1024's used an in-house made fader with a slider that actuated an AB Rv6 pot with a string/cog configuration.

they were nice long throw faders. Even had a halfway decent feel, and the pot was sealed from cigarette ash and dust and easily replaceable.

I can post photos/specs tomorrow when im back in the lab if it would be helpful.

Anything from Spectra Sonics is always of interest to me!

Philips MM1 desk - the The EL3671 fader module.

Note that these were faders linearized by slightly individually shaping the "drum" the moving metal band was turning (!!)
