Grenadier Models' figures were initially cast in an alloy of lead and tin, but in 1993 New York legislators nearly passed a public health bill barring the use of lead in toys and games. Despite the additional cost, numerous manufacturers anticipated parental concerns, similar legislation in other states, their own workplace safety, and they began using white metal alloys. Grenadier began converting its lines to a non-lead alloy they called "Luminite" in the winter of 1992. The use of non-lead alloy marks a clear benchmark for dating old figures. In time, New York Governor Mario Cuomo relented to hobbyists' concerns and exempted miniatures from the state's Public Health Law. However, Grenadier Models did not return to producing in lead.
