Thank you for the replies Steve, Bill, and Garth. They’re very helpful.

I should have caught the ATSF gondola. It was in my 1950 ORER, but I missed it because I was tricked by the way the entry for ATSF is parsed. It skips the number range where you’d first expect these cars to appear, only to show them on a later page. Of course I have encountered that before, but didn’t remember it in this case. Thanks to you all for getting me squared away.

All the best,

James
