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.
