I agree with Richard Hendrickson that photographic or other
documentation is
the best approach to determining the ratio of home road and foreign road
cars.
Beg to differ. Photos will almost always show a small portion - usually
that portion closest to the locomotive. Far better evidence, while hard to
come by, are conductors books, interchange logs, and yard jumbos. On an
aggregate level, the railroads reported the percent of home house and open
top cars at home and said numbers were published by the ICC, the AAR, and
Railway Age.

Assuming a typical value of
one car turn per month, the total number of WM boxcar shipments
in 1952 was about 27,000.
I don't recall ever seeing an cycle time numbers. I think it would be
interesting. But then I'm a data head.
