The tube would be a WD11. The large pin is plate. Two pins along side this one are filament. Filament is rated 1.1 volts @ 250 ma. The last pin is grid. This was one of the first tubes made to be operated off a dry cell battery.
Haven't looked at your pictures yet but probably a 1 tube regenerative receiver. These were popular in the mid 1920's. (Now if I just can type in all those characters.)

:I am sending you some pictures of a radio??? that I bought at a garage sale the other day. I don't know what it is, or how to hook it up. Do you have any sugestions where I might be able to find some information on something like this? The one tube doesn't have anything written on it. It has 4 pins, and one of them is quite a bit larger than the other 3. There is no socket on any of my tube testers that will accomadate it. I would guess it is used as a detector, but don't know that for sure. The two small pins across from one another seem to be the filament, as they are the only ones to show any resistance between them. Any thoughts you might have would be appreciated. Links to pictures below.I made you a drawing of the face plate on the old Westinghouse last picture. Hope you can enlarge it and read my scratching. Rick..
