Can anyne ID these small WE transformers?

[Opcom]

I found three Western Electric transformers with the markings below.

Does anyone know what they might be from? I guess some kind of radio set or something.

They are all the same size, silvery round cans with the seam around the bottom which is like a 1.4" deep 'cup', and the top cover is a single piece and has a radiused top edge and flat top. 1 7/8" tall and 1 3/4" diameter.
4 terminals, and two screw threads protrude from the bottom of each one.
Two are the same, a small output transformer. Maybe they are good for something, ham radio, or what?

I've seen similar WE input xfmrs on ebay go for a few grand each.  Check out what you have, may be worth big bucks.
