Wow, get a load of this!

Home made, but I can't tell much else.

Interesting.

Here's the other one

And now, the most interesting of all....

Does it go BOOM?

Probably the same as the model in the desk for demo purposes.......

Apparently these weren't homebrew - but actual production models. Radio Museum has a listing for Frank Porter Co. and lists 3 models: Coriola 7 (7 tube - 1927), Superior 25 (7 tube - 1927) and the Superior 436 (6 tube - 1926).... I suspect the dates listed may be off a couple of years - Shorpy dates the picture at 1926. No pictures or schematics are included. Since there seems to be 7 tubes, the radio pictured could be a Cariola 7 or a Superior 25.....

PS - I have the speaker to the far right (on the small table) - it's an enclosed horn - Bristol Audiophone Model C......

An early "B" battery eliminator? Quite the condensed form if it is.
