Two pair of HO scale wood beam freight trucks used under equipment of the US Military Railroads during the American Civil War. One of many similar types made by various builders, starting with the Pennsylvania in the late 1850s, this design was the last hurrah for the widespread use of wood sideframes in freight service.
54" wheelbase, canister coil springs, decorative spring plank columns. Flat faced journal boxes are of a type most often seen in Civil War photos by Russell, Brady etc.
This version mounts with a #2 screw (like those used by Athearn/Roundhouse MDC and others) with a recess for the screw head, and can accomodate a larger screw with a little reaming. They should look great under Alkem or BTS USMRR car kits and backdated MDC, IHC, and Mantua cars.
Requires 33" wheelsets with 1.010 inch or shorter axles (MDC, Kadee, Reboxx). Others may also fit.
Wicking in some thin CA glue will strengthen parts. Because of their fine detail, Frosted Ultra Detail is the preferred material, others will show varying degrees of surface roughness. The strong flexible materials will be crude and may not even print because of the thin sections. Clean with alcohol before painting. It particularly greasy use a toothbrush soaked in Bestine rubber cement remover. Acrylics recommended.
