Oscillodyne?

[Sandy G]

There were literally HUNDREDS of mfgers who rushed into making radios in the early 1920s, some made no more than a handful of sets before going "Toes Up", or going back into what was their REAL calling-A lot were furniture/cabinetry makers. I don't know, but I'd hazard a guess yr set uses 01As. They frequently get robbed from these old sets, as they're sometimes more valuable than the sets they're in.

thing is looking at the pics, im not sure its a radio at all. maybe some sort of signal gain device? i can see a couple rheostats in the pic, wonder what this was used for... definately cant wait to go see it in person.
