Oscillodyne?

Looks like a battery set to me. My guess would be 01a's also. Check the transformer, it's common that they are open.

It doesn't look like a common 20's battery set to me, either. I think superhets typically had 8 tubes (usually 199s). But the tuna fish can transformers scream superhet. Post this on ARF, someone there will know what you have.

Yep, get some 01as, and you can probably use a 71 tube for the audio output.

Did you check the underside? Sometimes there are elaborate instruction cards tacked there.

Thanks everyone for the input. I will definitely give it a good looking at when I
Go check it out this weekend, thanks to you all I have a lot more to go on. I'll keep you posted as I find more out and get some better pics. I'll ask on ARF after I get some firsthand info.
