They should be fairly decent perfomer, they did use the same chassis in a floor model as well. Depending on how many tubes it has it may have used a phase invertor or used the screen grid inversion trick that Philco was famous for. One thing to watch for are bad output transformers, a very common fault with early 40s Philcos. If the rubber wire is rotted it's a bit of a pain working around the pushbutton assemblies these sets have, the rubber wire will also go up inside the IF cans as well. Use vinyl covered wire in an assortment of colours for replacement, 18 or 20 gauge preferably.
By the way, the edge banding is a faux finish like dynoc so it will come off with paint stripper or acetone if you get it on there.
