Postwar Lionel 6464 boxcar mold variations

CW, I think the "ribs" are the same as on the top, only inverted. I have some that have it, and others have a smooth surface.

C.W., I am not an expert on 6464's myself, and I don't have a specific answer to your question. I only have 5 myself, 3 PW and 2 of the late issues. However, I do find them interesting.

I don't know if you're aware of the great articles that Mike Stella, Jim Herron,  Bob Mintz and  others have published in the TCA's E-Train publication. I could peruse them for hours (and have done so!) Here is the index; you may find an answer to your question in one of these articles:

Here is a great chart with all (?) of the 6464's listed, with pics:

Thanks for the replies.

I looked through the Bob Mintz and Mike Stella articles from E-train. I didn't see anything detailed enough to answer my question.

The car certainly does not have a reverse impression of the roof ribs, as Rob describes.
