The Style of Radio I Love - Take 2

Here are four more of my little guys! The first is made by Federal Radio and Television Corporation from Chicago. I've got very little on this set. I like the design and the stair-step escutcheons.
Next is my Simplex "X" made in 1934. I have never figured out if this is an "X" or a 10. Either way, it's very cool!
The next one is from General Electric and has a metal case. It's a K-41 set made in 1933. This was back when RCA, GE and Westinghouse all made the same sets - they just changed the names. The RCA version model number is R-17-M.
The last one I have nothing on except the tag with the name "Sylvan". I love the design although whoever had it before put in things I've never seen before. I'll have to take everything out and replace nearly everything. It won't be original but it will work!
