I just got this old Westinghouse battery radio. There doesn't appear to be a model number. It says licensed for amateur and experimental use only and made in East Springfield Works with two dates of 10-6-14 5-10-21. It uses one tube which is missing. What would the tube be?? It is a 4 prong tube with three smaller prongs and one large prong.

WD-11

Agree, WD11 is the only popular tube with three small and one large pin. Very expensive unless you buy or make a sub.

Should match RCA Radiola Senior schematic.

Here is a link to buy a made sub, or make your own.

I was able to match up a picture on the radio attic archives and I have a Aeriola Senior. Don't have the paper that goes in the lid. Any idea how I could get a copy of that lid paper?
