Erector Construction Sets

Erector metal construction sets were introduced by A.C. Gilbert in 1913. It was an early competitor to Meccano. Known as Mysto Erector until 1916. In 1930 A.C. Gilbert bought over the American Meccano factory. Erector lasted until the late 1980s. However from the late 1960s the company was having serious problems and it went through a number of owners (Gabriel, Ideal Toys & Tyco Toys) until it closed in the late 1990s. Meccano then bought over the Erector brand name in 2000 and now uses that name to sell Meccano in the American market.
