My name is Jacob Damron and I model the Rock Island and its passenger trains in the early 1960's. One of my next projects to expand my BX fleet is the Sunshine Models RI 20060-20069 10'6" aluminum box car (Jeff has already addressed my RI 20000-20051/20070-20084 research request). This car rode on Barber S-4 Swing Hanger trucks and I'm having a hard time locating such.
Does anyone know if these trucks are/were offered in plastic or brass?
