Both these classes had an interior height of 10'-0" and the cubic
capacity essentially matched that of the AAR 1937 standard boxcar. The
capacities were 40 tons or 80,000 lbs. Those are the built dates for the
original class M-15 with steel underframes and double-sheathed wood
superstructures as model by Westerfield. The cars were rebuilt with the
all steel wagon-top bodies between 1936 and 1937.

Yes, as stated the M-15K and M-15L used the original fish-belly
underframes. These B&O rebuilt boxcars are really not too different
than steel boxcar bodies placed on old USRA undeframes. The capacity for
the M-53 was 50-tons or 100,000 lbs.
I have posted this before, but the truck spacing on both the Sunshine
and F&C M-15K is too short. Although I have not built the model I have
considered using the underframe from the Westerfield kit as it is more
accurate and has the correct truck spacing.
It should be OK to use the West Shore M-53 kit with modifications to
model the M-15K because information on the blueprints states that the
body panels and end sheets are the same for the M-15K and M-53.
