Vintage Radio restoration
DaOld Man:
I bought a piece from a 1920 Tecla model 30 crystal radio. Trying to restore it.
I know this site is not geared for that but I was wondering if there is a site like this one dedicated to that subject, that i could join.
I am a member of a facebook group, but I like this format much more.
Thanks, and sorry for not checking in for awhile.

i'm not sure what it is you are looking for. when you say restore... do you mean restoring it back to working condition... or restoring it back to as it came out of the factory?
i mean, it's a crystal radio... theres not much to it as far as "electrical" goes. it's basically a coil of wire to adjust the volume, a tuning capacitor, and a crystal of galena used as the semiconductor diode to "power" the audio circuit.
me thinks it would be more of a "strip the finish off the wood and refinish it" kind of restoration. the information which, could be obtained from literally any woodworking website/blog/forum. reason i suggest a woodworking forum, is because it would probably have the most up to date accurate information regarding wood and how to prepare and finish it properly with today's finishes than a forum or site dedicated to antique radios.

Doesn't matter that it's basic internally. It still no doubt has bits and pieces to restore/replace. Bakelite knobs for instance. I totally dig it da old man. And I agree the forum format is best for these hobbies. Don't of anything of hand though.
DaOld Man:
Thanks. Heres a couple of pics.

What is missing?
two labels (GROUND and TELEPHONE)
one bakelight terminal nut.
One wiper assembly (someone replaced one with a variable capacitor.
One cats whisker assembly with galena crystal. (It was missing, I installed two banana jacks to attach a geranium diode to.)
Original box with instructions on fold down door. (I made the box in the pic, I only had a pic of the original to go by).
It works, but I havent put up a proper antenna yet, so its reception is limited. (A proper antenna is a wire 50 to 100 feet long, strung up outside at least 10 feet off ground.)
Here is the pic I had of the original:
