And as Tony pointed out in another email in a galaxy long ago
and far away, from April 26, 1956 to November 30, 1956, the car
wore the number 171490!

Also according to an earlier Tony email, the 110249 was built on
December 28, 1954.

Yep, all that's in the car ledger. The 171000 series was the "permanent"
number.

from SRI drawings. This car became 650831 in 1956, and was classified as
B-50-34-X at least as early as March, 1955.

Keeping track of SP freight car renumbering is fun!

The SP started development in the early 1950s, and turned it over (with
funding) to Stanford Research Institute (as it was then called) in 1954. By
1955, they were ready for a try-out, and a single car of Class B-50-34 was
rebuilt with the "beta" Hydra-Cushion and reclassified as B-50-34-X (it
became car 650831 after the 1956 renumbering: the real tryout car if not
the protoype).
