[AMRadio] Pot maker

[CL in NC via AMRadio]

The fellow I am repairing his HQ160 for, said to find at all cost a Q Mult/BW pot for his receiver and not try to repair the old one.  I contacted one commercial custom pot maker, but does anyone on this site have a recommendation for a custom pot builder?  I need a concentric shaft pot, the 1/4" shaft turns the 200 ohm section, the 1/8 " shaft turns the 10K and activates the SPST switch on the back of the 10K.
