Sensei Richard sez:
Standard of Indiana and Esso, being former members of
the Standard Oil monopoly, continued to contract with Union Tank Line for
rail shipments after the Standard monolith was broken up by the courts.
Pure Oil sold their tank car fleet to UTC in the mid-1930s and leased cars
from UTC after that date.
So, the P2K Type 21 cars with UTLX rreporting marks would be appropriate then? Or perhaps the Intermountain Type 27?
Out where God lost his shoes in the Pennyrile of Kentucky.
