If this set is anything like my model 39-40, you'll need to remove the bezel around the dial scale (it appears there are 8 screws). Behind it there will be at least two larger screws that are screwed into the dial face surround itself. If those screws are left in the chassis will never come out. Not sure if this set has a toggle off/on switch mounted under the wood to the left of the spindles in front of the grille cloth like my 39-40 or if it uses one of the pushbuttons for off/on. If it uses the toggle switch, the nut around the switch will have to be removed and the switch pushed back up through the hole to get the chassis out.

I would strongly recommend you don't continue to try it out until the power cord and capacitors have been replaced at minimum and even then using a variac and monitoring current draw. There's a ton of brittle, cracking wire under that chassis with a lot of potential for shorts. A lot of the wiring will need to be replaced or re-sleeved.

The radio station call letters and plastic covers are attached to the dial bezel which you'll be removing anyhow to get the chassis out.

The dial light bulbs themselves may need to be replaced and glass dial scale probably needs cleaning (CAREFULLY as you don't want the numbers to chip off of the back side) which should brighten up the dial area for you.
