Keith ,,,I have one of those radios,but the cabinet is a little different..It looks like yours is fancier around the dial.. Mine is an S-7 [ I believe]
I picked mine up at an antique show for $80.00 and I had to redo the whole cabinet.. I also recapped the radio and now it plays very well. I did not find it hard to work on at all. There was lots of room inside
I am posting a couple of photos of mine..
