What you might want to do is take one of the freight cars and clean it up to what you think is a presentable state. Keep track of the time it takes and by multiplying you will have a good idea how much time you would have to invest if you chose to go that route with all or even some of the stuff you have. Is the elbow grease necessary going to be worth the effort/time spent?
A couple other things: There are still some aficionados out there for what you have, but their numbers are nowhere close to what they would be for old 3 rail stuff. Most of the 2 rail crowd is interested in accuracy and detail, and while your stuff was respectable for it's time, the new stuff available has pretty much left it in the dust.
If you have the time to spare, I'm guessing you would do best on Ebay.
Good Luck,
Simon
