[TenTec] 238 tuner knob questions

I found a review of the 238A on ARRL site and the photo shows the inductor is marked as 0 to 30.  So I assume this is the multi-turn knob. It would be nice if a retro-fit to this mechanism could be done??

>I am looking at replacing the Capacitor and Inductor knobs on my 229A tuner.  I'd like to get something closer to the knobs on the Orion.  I've been looking at the 238 and 238A/B tuner knobs and it "looks" like either will work.
