Default Re: RAP 646 restored

Yes they do use a Muirhead drive, or possibly a copy.

Great set, well done on the restoration.
I have one of these, had it for over 20 years, & still going strong after my original restoration.
Definitely worth keeping. When I had mine on display, I had a mirror on the wall at the rear of the set, - always caused fascination to visitors.
