restoring a Farm radio

here is a farm radio i was working on I have stoped because of no schamitic. I need to try and find one so that I may get the proper voltages to get it going
here are the rezized pics

1.5 vdc for the filaments, and 90 vdc for the B+, those were pretty standard values for a lot of the simpler farm radios. And Yes a schematic will help a lot.
How many wires come out to the plug? looks like it's 4, but can't be certain from the photo.

Re farm radios. Are we supposed to guess as to brand, voltage, and model. Please include same in postings. Also, I'd like to have one. OT.

For the voltage of tubes, look-up in a tube handbook for nominal voltages. Also figure on replacing all caps. OT.

Thanks oldtimer I am actually selling this radio it has been recapped and
chassis cleaned needs dial cord i have pointer $25.plus shipping takes it

This looks like a Clarion C108 made by Warwick Manufacturing. Does it have any information on it such as "WM Co" on the tag?
