Capehert 10-12 info needed

I just acquired a 1938 Radiobar 3-3 (also known as a Philco 38-3-3XX "Georgian") that has a Capehart 10-12 drop changer that I am in the process of restoring. I've restored many radios, but this is my first changer. Does anyone have any info (service manual, etc.) that will aid me in cleaning, lubrication, and adjusting of this unit?

Also, has anyone ever heard of or seen this 1938 Radiobar "Phonograph with Philco" unit?

Thanks,

Pat

This record changer is covered in the public domain Rider's book "Record Changers and Recorders".

This shold be the one:
