Briggs Models has released their first O scale kit of a Canadian Pacific “Minibox” Boxcar. This is a #d printed model which includes both AB and K brake details, A ends with and without lumber door, and material for ladders and details. The coupler pockets are scale and can be modified to fit Kadee couplers.
You can purchase these kits individually or in packs of five. The kits are highly detailed but do not include trucks, wire, decals, or couplers.
