This in a 2mm:1ft scale model of a British Ministry of Ware designed Rectank wagon, used for transporting military vehicles during World War 1 and World War 2. Between and after the wars, they were used in the UK for peacetime traffic (often fitted with bolsters). This kit includes the wagon body and a pair of NEM-pocket fitted 5'6" diamond frame bogies, though N-gauge Society diamond frame bogies can be used instead.

There is a sprue for the tool tray, a pair of lozenge-shaped toolboxes, a pair of low-profile vehicle chock 'bolsters', and brake handwheels (use the 5-spoked ones, plenty of spares and some 4-spoke and 6-spoke ones as well that you can use on other projects).

You will need wheels, and NEM compatible couplers (traditional N-gauge, knuckle, magnets, whatever) and fine wire (0.2mm Nickel Silver is best) for the trussing if you want it and as a spline for the brake handwheels. See my TT120 model of the same wagon for a little more information about that.

Wheels can be N-gauge profile or 2mm FS profile, axles should be 14.8 mm over pinpoints (e.g. Peco) but if any longer you will have to be very careful cleaning out the pinpoint cones in the bogies and when fitting the wheels. The wheels should have 8 spokes ideally, and if you want exactly scale 2'9" wheels like the prototype, let me know and I'll upload them (0.25mm lower ride height).

PLEASE NOTE the photo shows a Shapeways printed 2mm/N-gauge rectank which has been painted, standing in front of of an unpainted one at TT120 scale. Crystal MJP will look similar but slightly yellowish.
