These are the real thing from the late 1970s. These are flat-bottomed knobs (as shown below)
and both have the rough knurl. I took the allen set screws out when I polished them. The screws
are included and will be inserted before shipping, promise.
Asking $15 for the set, includes U.S. or APO shipping.
They fit great on Clarostat Mil Spec pots! Click here to see the Clarostat pots.
