Daven true vintage 1970s rotary pot ladder-network 

~20 step, 2 dB/step. smooth rotation (no detente). taper to "off" cue function. 

It's the standard size 1-3/4" diameter. Typical 1/4" shaft; hardware seen on shaft is included. Nominally 600/600 ohms. Could also be mounted thru-panel with two guide holes on each top. 

Note the track disc on the inside has a portion cracked away, but nothing that was part of the contact track - the pot is still functional.
