Got another email from Jim King, here's what he said:
I have 26 kits “sold” including yours and the 2 unknowns on your list. I really need to hit 50 to justify the time and expense but we’re already halfway along so there’s hope.
Bob3, email Jim directly to let him know you're interested, his email is at the bottom of his website:
Most of his offerings right now are S-scale, but at least he's listening/watching to us O-scalers!
