Hoping and wandering if these fit together?

That knob is almost certainly 1/4" (6.35mm) I.D. -- standard shaft size for the potentiometers on Warlords, which is also the same as the TT2 shaft.

The knobs to watch out for are 6mm I.D. ones like for the ones for the Ultimarc SpinTrak.

Funny you should ask!

I ordered that Atari knob and it definitely does not fit the GRS spinner. I ordered the TT2 and waiting for it to arrive. I assumed the TT2 has a 1/4” shaft but couldn’t find documentation.  I assume it does because back when I built my tempest Bartop I used a NOS atari knob on a TT2.

I’ll report back.

Standard 1/4" Alloy-steel shaft for the widest possible selection of spinner knobs.
