This is a 3mm:1ft scale model of a complete 50t MoW/British Railways Warflat wagon used for carrying military vehicles. The bogies and wheels are included as moving parts. The bogies have NEM pockets. If you break the bogies, they are available as spares. To replace the bogies or just remove them for cleaning, break the tages holding them on the cylindrical pivots and they will slide off. To keep them on after replacing, feed a bit of bent wire through the tunnel in the pivot so that it sticks out a bit an each end. To use the NEM pockets on sharply curved track you may have to remove the rail support jacks under the headstocks. In peacetime use the jacks were generally removed anyway, leaving visible scars on the headstocks. Many Warflats became bolster wagons in British Railways service.
