Was this Challenger offered as a kit or assembled as a one off? Except for the driver style, it appears to be a rendition of a SP&S Z6. No matching tender was available when bought and no marks of identification can be found. Any help identifying the behemoth will surely be appreciated.
I have endeavored to tidy up rough surfaces on the rear engine and get it operational.
A few rough castings and stamped brass domes attached crudely. Compared to the drivetrain, the boiler assembly appears amateurish. I may tackle an entirely new assembly.....?
