Correct you are! Inside label does indeed say Montreal QC on it, and I'll gladly post some pics once I finish removing the (literal) mouse's nest of fiberglass insulation that was stuffed between the chassis and the cabinet... I think it was the little buggers that gnawed through the tuning cord too.
All in all, the cabinet, grille cloth, and set are in pretty good condition- the room we stored it in was dry- There were some books from the 50s-70s in the same room which were still in near-perfect condition- no mold or mildew on them.
As given by my username, I can sniff out a C64 at 50 paces, but have no experience with old radio equipment
I'll get some snaps of the tube layout diagram too, as it may be of some help.
Cheers, and many thanks,
