Note: My apologies for the off and on rejections, if it's not one thing it's another: I've made this model comply with the new 0.6mm wall thickness rules by adding a little material to the deck underside so it should no long get rejected. Recently it was rejected for the sprue between the axles, something that worked fine until now. That part's gone, so what else is there to reject? The spokes in the wheels maybe? Jeez Louise A kit to make six four-wheeled freight cars. The prototype for this car resides in the Baltimore and Ohio Museum and is of a type commonly known as a flour car, since its original purpose was to ship flour barrels between Ellicott's Mills and Baltimore. Contemporary roads used similar cars. Although it dates from the beginnings of railroading in America, this design is virtually the same as many later four wheeled mine trams, slate cars, and mill carts. This version is equipped with Winans patent low friction journals used by the B&O in the 1830s. Cars couple together by fitting a U shaped wire, link and pins, or scale hook and chain (not included) into the .019" holes in the drawbar ends. The 9-spoked wheels provided will operate but aren't recommended for extended use. For that use 28" wheels with .540"(13.8mm) length axles (FVM, NWSL etc.). 33" low profiles will work but may necessitate slight modifications to the underside. See also part R13b for the same cars with separate underframes, part R14 B&O flour cars with conventional journals, and a mixed set of 12. Because of their small size and fine detail Frosted Ultra Detail is the preferred material. Clean with alcohol before painting, acrylics recommended. Part number R13.
