My most current price info is the "Collector's Guide to Antique Radios", Fourth Edition, copywrite 1997. This is well before the "eBay phenomenon" which has led to an increase in prices for a lot of collectables. So, don't pay too much attention to it.
It lists the Philco 37-60 (1937, btw) as ranging between $100-$145. That may still be a fair price for one in good, ORIGINAL, working condition. If it's been stripped and refinished, that's never a good thing.
Here's one that sold on eBay recently:
