Terd,

I've CC:ed this back to the group as someone else may find the data
interesting...I think John indicated that the H31a was, as you suggested
earlier, a "test" car. Then, they made some changes and produced the H31b.
I noticed some interesting roster info on the page you suggested regarding
the conversion of the composite H31b to the all steel H31c:

H31b H31c
492 5 April '52
266 225 Oct '53
12 482 Oct '58
12 475 Oct '63
3 276 April '68

Sooo, the 1966 photo in PP3 is most likely a scrap line, although the
reporting marks don't appear to be "whitelined" in the photo. The amazing
thing is that 3 composite hoppers are still listed in 1968!!! Based on
this data, I'd say Mike Brock needs one of each class <G> for his Sherman
Hill layout ;^)

Happy Rails

Bruce:

Here's a link to the info. There were slight differences as you
indicated, although I don't know why (they're not so great as to indicate
completely different types of cars). Any ideas?
