Many of the Kibri kits have a traditional European feel. In earlier days, Kibri marketed several individual kits in one larger master box; these kits would have a common theme such as a town or a factory, along with several accessory kits that added fences and such to the assembled group of structures. I never put pencil to paper to determine if this was a less expensive approach, with the cost of the master kit being less than the combined price of the individual kits together.
In any case, the Kibri structures are quite nice, very cleanly cast and well detailed. A few can be “Americanized” for use with American prototype locomotives and cars.
