Welcome to the forum Ian,
Here’s a link to the Radiomuseum website for the schematics and other info: https://www.radiomuseum.org/r/rogerstube_majestic_montcalm_ch_54.html
The Rogers 10-65 and 10-66 are also identical if you find a schematic for those. As to value, It often depends on where the radio is. For example in Montreal which has been around for a long while, consoles are a dime a dozen with good unrestored examples going for anywhere from $75 to $150. West of Ontario, they become more scarce and therefore a little more expensive. Unfortunately, for antiques in general and radios in particular, post baby boomers for the most part see no use in old things. Example: here’s a 1938 Philco I completely restored and refinished with the original grille cloth and I can’t even get $120. for it : https://www.facebook.com/marketplace/item/813414002560227/?ref=search&referral_code=undefined Been for sale for a month.
That being said, your radio is nice shape, but I wouldn’t worry about restoring it. Just fire away when you run into questions. Plan on replacing all the paper capacitors and the electrolytics as well before even contemplating firing it up. A good place to get parts with quick delivery is : https://www.justradios.com/ (Canadian company )
Good luck, Gary in Montreal
