This past weekend I picked up a P2K Type 21 decorated for Philadelphia
Quartz in a black tank with yellow lettering. The car number was 506.
Knowing that P2k was very good about only putting accurate schemes
on cars I
am sure the P&L is correct. I am trying to determine what trucks we
applied
to these cars. A photo of POX 806 built in 1928 is on page 113 of
Kaminski's ACF Tank car book, but I believe this to be a later Type
27 based
on the build date. The series doesn't appear in Ed Hawkins roster
in RPC
though. Given the way tank car leases changed, that is not surprising.

Any help on the trucks would be appreciated.

PQX 805-858 and 512-518 were essentially identical; both series were
8K gal. Type 21s. (Type 21s continued to be produced, at least as
late as 1929, after the Type 27 was introduced). Both series came
from the builders with 40 ton ARA trucks with spring planks (i.e.,
Accurail). Philadelphia Quartz owned, not leased, their cars, so
their fleet remained unchanged over the years except when they
purchased new cars.
