I would agree with some of the list above, since McKeen's were available in 55'
lengths, but maybe even the biggest hassle beyond body forming in scratch building
these is that front truck (and I don't know if the rear truck has been made by truck
sources, past and present, either). I could build one, except for that front truck...
I might be able to cobble up the rear one out of a coach truck or something. But
without that front truck, it is not a Mckeen but a caricature. To save money, make
it conventional, and let the people who do add electronics to a lot of rolling stock, do
that, or have it done. Unfortunately, $250 may or may not get you a 3-D printed
shell...but hey, I'll take a shell. To get that price we are going to have to resurrect
Ken Kidder, or maybe Louis Marx.
