This is an American Model Builders 870 HO Illinois Terminal Bay Window Car Wood Caboose Kit Laser-Cut Wood. Accurate laser-cut wood constructed caboose body kits ready for detailing. Trucks, couplers, ladders and decals not included. To further enhance these kits, Detail Associates produces an AMB Caboose Detail Kit (#229-550, sold separately) with ladders and pre-bent wire grab irons. In the early 1940s, the Illinois Terminal shopped five former 4000-series wood-cupola cabooses of 1912 design, converting them into bay window cars. The cars saw systemwide use and lasted well into the diesel era. The kit includes cast-resin bay windows, laser-cut end ladders and brake wheels, and a drilling jig. Photo shows assembled and painted model - assembly required.
