Similar make to the Greenville Woodchip Gondola with nickel-silver etched parts, available as kit or RTR, with real wood or resin load. So far I identified two user for this design: NS and FPBX, if you know more feel free to post some pictures. Pictures shows the the car in FPBX colours with graffiti and waethering.
O.k., if somebody is interested, same pricing as the Greenvilles: Kit incl. load and decals of choice (NS or FPBX), no trucks included: $40 +shipping Complete cars $90 + shipping, weathering extra. Real woodchip loads: +$8
