Hi Robin and welcome to the fray,
I think Mike has the answer. Chassis is a 20. If it were a 21 it would have a large round filter cap. The 20 uses several in a tin can like this chassis. The 90 would have a singe section volume control only the older non avc sets use the dual control. I would suspect the knob on the right is to adjust the tone the 20/21 didn't have that adjustment.
Cabinet is for a 90. The holes for the chassis to the wooden base don't align. The 20/21 only use three bolts the 70/90 uses four.
If you could post a pic or two of the top and bottom of the chassis and the base board that arn't so close up I can a little bit more abt it.
Best Regard's

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
