Questions on SAL B-7/AF-1 boxcars

salfan2001 <ThisIsR@...>

I have a few questions relating to SEABOARD's B-7 and AF-1
1)Did they have drop end style grabirons? The photos I have don't
really show the grabs too well.
2)What kind of handbrakes did they have?
3)What kind of trucks?
4)I'm assuming by the late WW2 years or late 1940s these cars would
have had steel running boards. Correct?
Thank you for your assistance.
