This falls into the "you are not going to figure out why, or change what, manufactureres make, so why don't you just shut up!" category....but I am ignoring my own advice for the moment. I just got an email
offering a whole lot of "convention" cars. Now these are fantasy cars....I think the last "convention" cars I actually bought were believable flat cars loaded with marble that TTOS offered for Marble, Colorado. They did not have the mfr. brand on them (maybe underneath, but not visible), and they were in possibly prototypical colors (not flourescent orange). In just about every train show is a book dealer with a book on some obscure defunct RR I have not heard of. A number of obscure RR's died after WWII. I would be interested in maybe buying plain Jane boxcar red 40 foot house cars lettered for the once existent "Podunck and Pacific", or other
obscure defunct RR's. if done in a short run not likely to be repeated by that mfr. They have to be good models,
too...not toy rude approximations. TTOS has my thanks and admiration (and money), and other club branches
sometimes generate a prototypical car for a convention. They may have a market here. With all the real cars
to choose from, why invent a fantasy? Beatstheheckoutame.
