Example of the Italian Spica class torpedo boat built during the 1930s, which was equiped with armaments similar to destroyers. They are smaller than destroyer due to the limiting clauses of the Washington Naval Treaty in 1922. The Spica class was designed to be deliberately smaller than the clause requirements of the treaty, so Italy could build an unlimited number should they have wished.
Simple one piece model design for smaller scales and tweaked to ensure as compliant as possible with Shapeways. Designed by Philip Warnes and can be used at a larger hex scale with his SeaLion Supremacy
game, or any other naval tabletop game that uses this scale.
