@Rusty Traque posted:NP's FT's, F7's, FP7's and F9's all had D/B's. I see no reason why the F3's wouldn't. Overhead views are hard to come by, but in this shot of the 1947 NCL the D/B vents are (barely) visible.

Then why would the models of them, and the NYC F3s not have them? It seems like a huge oversight for such an expensive model.

This was confirmed at the club after a long discussion between members, comparing the Lionel, MTH and 3rd Rail F3s.
