Some decades back I had the great good fortune of having Bob Moog make a Model 91C theremin for me. It is of course a treasured instrument and has seen many adventures. I know that Big Briar did not make many of these, and I have become very curious as to how many were made and what has become of them*. Any information would be greatly appreciated.
*I do know of the one that went up for sale on eBay in 2019. That one did not appear to have the gold-plated antennae, which mine does.
