Another of my forays into the bottom-most boxes revealed my good 'ol Monitor model of the famous ACW ironclad. The model is some 10" long made very simply from foam core and a plastic lid for the turret; a straw for the funnel and painted black and crudely drawn iron plates using a pencil.
The intent was to make several of these size of ships for games but so far have failed to do so. While I like the naval aspect, I really never seem to play it.
