Hadley 621 Knob Replacement

I have a Hadley 621 Preamp and the knob (bigger one) for the input selector was missing when I first purchased. Does anyone who is familiar with this preamp know if the knobs are being reproduced?

I think I have one for you... it's 32mm diameter, the same size as the Volume knob. Please measure yours.

The Hadley is a rare piece; I doubt parts are being reproduced. Have you looked inside the preamp? It's truly a thing of beauty!

I measured the my volume knob and indeed is around 32 mm in diameter. Do you have the exact knob that is from a Hadley 621 or some other knob but with the similar diameter? I also PM'd you as well and your help is greatly appreciated!!
