Found this in a little antique shop a few weeks ago

Inside it was empty apart from two of these lying in the bottom

Anyone care to hazard a guess as to what a Gecophone was, and what the valves are?

Gec battery valves probably 1920's
There should be a number somewhere and if that's is a BBC logo they are early 20's

Definitely said BBC, and Marconi. Hard to make out anything else in the short time I was in there but in the right light there was a bit more script which could probably be decifered.
