8 pairs of wooden passenger car trucks with 5' wheelbase. A common design for small passenger cars, cabooses/waycars, drovers' cars, milk and express cars, this truck was popular from about 1880 to the end of wood car construction. Based on a CB&Q No.7 truck used under waycars from 1880s-1980s.
This version mounts with a #0 or #00 screw. Made for 33" low or standard profile wheelsets (Atlas or Fox Valley Models with .553" length axles, other version uses MTs).
Because of their small size and fine detail, Frosted Ultra Detail is the prefered material. Clean with soapy water or alcohol before painting, or with Bestine rubber cement remover if parts are particularly greasy. Enamels or acrylics recommended. Part Number T57sa Contact firstname.lastname@example.org for painted models with wheels (~$6/pr).
