Plans for a scale model replica of a WW2 armored engine with panzer wagon that can be built in paper, card or brass.
This is a highly detailed, high difficulty model recommended only for someone who wants to make an absolutely unique diorama.
Depending on your level of determination you could possibly power the engine unit and have an amazing piece of operating rolling stock;.
Comes to you in HO scale but can be built in OO and TT also.
