Check out the lateral on MILW 7065 -- the long running board
looks like a standard Apex grid, but the lateral looks like a
perforated metal plate! I've never seen that before.

Tim,
Recall the overhead photo of MILW 21520 on page 55 of RP CYC Vol. 13.
It had an Apex longitudinal running board and the latitudinals were
wood. The 21520 was built in 7-44 while the #7065 photo was an auto car
was built in early 1944.
Regards,
Ed Hawkins
