Ron,
The only Monon I have right now is the frame for the 40' flat. It is a 1 piece casting and I include a laser cut deck for $15. It is the same as the one at Linden. Monon used these cars as the base for many of the MoW cars and sides can be added for the wood side gons.
If I get around to it, I will have passenger car sides. I have about half of the masters done and will even have the original hospital car sides. There will also be sides for LYNNE or #2 or what ever its called.
I also have 25 of the transfer cabooses in the works and have had requests to rerun some of the Riders.
I do have flat cars for GN, Seaboard, MP, WP and M&StL and 40' Combo door sides for NP, GN and CB&Q and am working on flats for CB&Q, another MP and Southern.
