According to my info, SAL 13000 series was 1937 AAR steel box cars. But that is from the 1960's, for what it's worth.
Thank you for the SAL JPEGs. I still have one question about the B3s. I have a Jpeg photo sent to me by someone,whose name escapes me now, that shows a B3. It appears to be numbered in the 13000 series but you can clearly see the class notation B3 to the far right of the wooden door. I know B3s were numbered in the 12000-12999 range. The B end also appears to be flat with no corrugations. Any ideas?
