Thanks Grampstrains,
That's good to know. Is there a specific set of car models from the era or is it more of a generalization? Really looking forward to getting these on some track.
TrainsRMe,
I think I found the missing car, it's 16023. Here's a pic I found elsewhere:
The only listings I've found for it say 1990's though it seems to have the same stripes with the silver car color instead of a middle white stripe. I may have to bid on it...
Yep, the B-unit keeps the profile nice and even.
