These are the ones that used to have the broken tooling, right?
That's what I remember hearing, probably true since it's been years since they were offered. I have one I can't find that I built from a kit they used to offer.
I am no student of tank cars, so I don't know about how accurate they are, but the old ones were nice looking cars. The photos of the new run looks nice as well, if not identical. Wish I could find my old one to compare.
I'll be in for some of the red Mobilgas cars when they are available. I see those a lot in photos of 50's era freight trains. Bet those go fast as well. The union starch cars are intriguing to me as well.
