I don't know about Frank and George, but Tony is made by "Golden Age Reproductions" I bought a kit on ebay recently and found they have a website and still make kits.

The kit is 24" ws and I scaled up to 1/16 scale. My plans now have a ws of 28" like the Zero. The kit is for advanced builders with all contest wood. I broke a piece just looking at the contents of the kit.
Here is a link I found to some interesting info:
