"Why do you think the Ohio Cities Gas Co.car was built by Pennsylvania Tank Car?
Brian Leppert Carson City, NV"
Standard Car Construction Co. (STC's predecessor) started in 1915 and didn't build cars in quantity until 1916, while high-walkway cars with the stereotypical "STC" underframe appear in the ORER entries for Pennsylvania Tank Line (PTC's leasing arm) as early as 1912.
