T gauge (1/450 scale) nuclear flask wagon.
This model has been designed to fit the Eishendo adjustable chassis. Note that this chassis wil need to be cut in a different way to that in the instructions, becuase this wagon is shorter than its designed minimum length. However this modification is no harder than the described recommended way. The picture of the separated body and chassis shows how this is done.
Due to the open design of this prototype there is not much space to add weight to this body, but I have left the container part hollow so that this can be filled to help.
