Train Miniatures Question

I agree with Gary, I think the TM FA's went to ConCor then to Walthers, same as the Cox GP9 went to Walthers, too, I think. Trouble is I don't know if Walthers designed their drive to fit the shell or redesigned the shell to fit their drive. If you can find the Walthers they are usually pretty cheap at shows, I got them for $20 ea last year.
 
Glen,
I think that I have 1 or 2 TM FA A-unit shells (undecorated).
I can confirm tonight with a search in the basement.
Powered or dummy?
What's your pleasure?
