Late 50s philco curb find

[JGlenn]

Ive wanted a 50s tv for as long as I remember and saw this the other day sitting out in the rain sadly. It was still out there today and it seemed to be in decent enough shape so I grabbed it. It looks like it could be a 56 or 57 philco diamond series? but the back panel is missing and its pretty grubby back there. Its marked 7L7 U on the chassis and 10302017705 and has a 21AMP4A picture tube in it which is a westinghouse and appears to be dated '63 so it was probably replaced at some point. Id like whatever info anyone has to give on it. Im really not sure what to do with it yet at this point. It seems like there may be some missing parts but it may still be salvagable although it did sit out in the rain for a long time Ive never taken on a tv resto before and im not sure if I could handle it. Ive redone a couple tube amps before but this is a much bigger project.
