I can sort of give an estimate as I have carried out electronic restorations for people before. First of all if it's a 1939 model year Philco the power transformer has rubber/gutta percha insulated wires, and they MUST be replaced, some of the other wires it depends on the condition, if it is still soft and flexible.
The 1939 Philco models typically used Bakelite knobs, so if they are all there they do not need to be replaced. However if the set has pushbuttons the pushbuttons were made out of Tenite plastic which usually deteriorates, warps, cracks, falls apart, so those typically need replacing. The dial and the plastic lens may or may not need replacing, it depends on what shape they are in. The dial escutcheon is brass, so if it's there it will just need to be cleaned up and possibly repainted at worst.
The 39-31X is the console version of a Philco model 39-30, Bob Andersen has a restoration series on You Tube if you want to watch it, and there are a few restoration threads about 39-30-s and similar sets on the forums as well.
Barring anything seriously wrong, such as burned out coils, a power transformer, and assuming a bad output transformer, and a rewire, capacitors, resistors, I would guess about $125-150 or so, that's just the electrical part, at the higher end if it needs tubes. If the power transformer is bad $200+. I may be a bit low though, but restoring a radio isn't like painting a fence, you can't just look at it and say it will take X number of gallons.
