I think your radio is basically a SM-60 B. Here’s a link to the Radiomuseum site. The tube count and type looks to be the same as yours, but you would have to pull and identify more tubes, but the 80 shows up. Looks like only minor differences on the cabinet.
Hope it helps, Gary
p.s. Just looked again and it’s only a 7 tube chassis. Close, but no cigar.
