John B. W. Tunstill (born 1939 in London, England) is a game designer known as a collector and maker of lead soldiers. He began collecting them during World War II while living in London. By the age of 9, he was casting lead figures on a gas stove using aluminium molds.
Around 1956, he joined the British Model Soldier Society and founded the War Game Section. He also started the magazine Miniature Warfare and has been the publisher of Wargaming Magazine.
On his passport, he described his profession as "alchemist", stating that he manufactured lead soldiers and sold them for money, the equivalent of gold. Since 1983 he has been engaged in buying, selling, and restoring medieval country properties in Umbria in central Italy.
Tunstill served in the Royal Air Force for five years in England and Cyprus.
