Garrett and I have been doing some talking. I went back and did a little research. There are some tanks we could do by kit-bashing. I doubt anyone is going to do the details for us, so we may have to do them ourselves. But, you are right, we need some of these parts badly....
Beofre you guys go spinning your wheels, you should know that three different mfrs. are doing serious R&D on steam era tank cars. It's way too premature to talk about details, but I'd wait to see what develops in the next year or two.
