Model railroad freight cars and accessories. N Scale (1:160), TT (1:120), and HO (1:87). For more info go to: http://theuniverseas.com/bvmodels
Overall, the freight car models just require trucks/couplers, cleaning (use Bestine), some sanding, paint, and a brake wheel (N MT Miner Wheel 1063). Some parts of the models are delicate, due to the nature of the prototypes. In general, the most delicate parts are the stirrups. If they break or arrive broken, either glue them back on or use the opportunity to replace them with wire/etched metal, which is more durable and more true to prototype anyway.
