Default Re: Help to Identify Marconi 3 valve set "EtherPus"

I expect the only Marconi connection is a license plate ("Royalty has been paid on this apparatus...", or whatever the wording was). Trademarks were zealously guarded and Etherplus existed as a brand for valve holders, potentiometers, etc., so my guess would be that the company responsible for those decided to try marketing a few complete receivers, or perhaps kits. That would make it quite a scarce, possibly a unique, box, but the downside is that even a photo of the complete set would be a very fortunate find.

I'm not sure where my little collection of Broadcaster trade annuals is: those carried comprehensive lists of trademarks, who owned them and the categories of item they were used for. I think my earliest is from 1933, which could be too late for the enterprise behind the Etherplus brand, but if not it would at least provide the name and address of the manufacturer.
