Hopper car builder

[Larry E Shankles]

Anyone know who the builder of GN 2-bay hoppers 73200-73699? I have the builder identified as SS. What does this stand for? Also do you have build date?

Larry-

Could it have been Standard Steel Car Company? I was browsing a non-GN book, and saw this builder's name mentioned.

Ken is correct, and they were built in 1931.
