Fellow with the RCAF transmitter on Ebay is NOT George. Was my hasty guess.
I do not know the status of George.    G.B. had a lot of unique radio items

on Ebay maybe 3 years ago now. However, even for something really unique,

such as an early version GO transmitter, the possible buying audience is really

tiny.  I suspect next to nothing of his offerings sold. I thought the

commercially modified ARB he had was pretty unique and interesting, and

that “someone” should save it, preserve it, but I couldn’t marshal the time

and energy…
