Yes. There are several examples of these Frisco 4-8-2's around (Mobile has one - in sad shape, though); Frisco gave several away. But, like the MoPac, the Frisco was mostly out in that Big, Anonymous Area that just generates little modeling interest. It did get as far East as Mobile and Pensacola (FL), but most of it was in the area that's not Western, not Midwestern, not Southern. Katy had the same problem.
So I'm not surprised about the kinda silly relative lack of interest - but I'd buy one.

Boomer - the Frisco heavy 4-8-2's were indeed germinated from the USRA Heavy 4-8-2, but are quite different from them in many ways; they don't even have the USRA "look" - Frisco built the boilers lower, which made the domes and stack higher (almost earlier-era looking).
- The A&WP (and corporate sister Western of Alabama) had no 4-8-4's. They had 4-8-2's, some from the FEC, USRA Light Mountain-based, with many detail differences. They had some really big Mikados.
- I had hopes for a NC&StL Dixie in brass from Weaver (I've requested it more than once) one day, but that apparently is not going to happen now, for sure...and I doubt that 3rd Rail will bother with anything from this part of the country (California's perspective is...distant). I'm going to have to build one; I have the frame/running gear donor picked out.
The Dixie is so good-looking (but in as-built form only!) that it can stay in the same room as the N&W J 4-8-4 and even the Dreyfuss Century and Dreyfuss Empire State Hudsons.
