I am partway toward collecting the parts of 'bash a St. Louis & Iron Mountain 4-8-0. I have just purchased a partly built 0-8-0 kit that will supply the main frame and the drivers; I am still looking for a similar ten wheeler for the cab, pilot truck and beam, and firebox.
One day, I hope to have a MIB example of all the kits and the R-T-Rs.
