I think that I'm flattered that a big wheel Case was chosen for this project over all the other brands that were available. I'm sure that the builder had his reasons.
In my opinion, the asking price seems very reasonable when you consider the amount of work along with the cost to create this novel piece of equipment. I'd much sooner see this done with a Case than to watch a bunch of brats deliberately destroying tractors on Youtube.
Would that not be a cool unit for parades? Would youngsters not have a blast riding in the cars and waving to people during the parade?
The thing is....it exists. Someone will hopefully snap it up, restore the train and then make a lot of people happy with it. The tractor will always be there when the fun is finally over for the train.
