Not a great surprise, but now that my little stash of Broadcaster Trade Annuals has turned up I was able to consult the earliest of them, 1933, for Etherplus as trademark, M. & A. Wolff, Mandaw, and... nothing. Doesn't of course necessarily mean the company wasn't still a going concern, just that it had very probably ceased all activity in the radio field by then.
