Originally, all scale models produced were made of metal. Early models, produced for miniature wargames such as H.G Wells "Little Wars", were hollow cast and made from lead. These were not made with painting as a consideration, although could be painted to help distinguish forces and armies at a glance. Models continued to be made from metal for many decades, with the models produced by Jack Scruby, credited for the rebirth of the miniature wargaming hobby in the 1950s, being made from type metal. These would be hand sculpted in clays then cast into a mold to be used to produce copies.
