Radiola/Electrola RE-57 advice

[PaulOF]

Kind people,
I'm picking up a Radiola/Electrola RE-57 this weekend. I've restored 40's and 50's radios, tv's, and amps. I've restored early mechanical acoustical machines. But I've never done anything from 1931 before, and I know almost nothing about the electrola pickups. Looks like it maybe contains a big horseshoe magnet with a moving coil?

Anyway, I would be deeply appreciative of any advice/experience you might want to share with me about recapping/restoring this thing. And if anyone knows where I can get schematics/manuals for both the radio and the phono amplifier, please let me know. I'll post some photos after I pick it up Saturday.

Let me thank you in advance.
Paul
