Primus Ferire
Exact item shown, Arra π Line Variable Attenuator. The "knob" on this unit is really a coupler to a 1/4" fiberglass shaft that had been snapped off - if you don't want the coupler it is held in place by an Allen headed set screw, you can remove it and there is a standard slotted shaft.
