This thread is interesting:
https://www.vintage-radio.net/forum/...hlight=emitron
The photos below are of an Emitron that sold on eBay and on the 18th July 2011 I sent them to Simon Waughan. Unfortunately I can't remember if there was any relationship between this and the donation refered to in the thread above. Perhaps Simon will see this and remember.
I think this was in response to a message I received on the
www.405-line.tv forum but my link to this no longer works.
