Road factory became the company headquarters for over 60 years. In 1920 the company started to produce 0 gauge model railways, and this production line continued into the 1960s. In 1922, Meccano Ltd opened a factory in Elizabeth, New Jersey where it produced its building sets for the North American market. In 1927 it started producing clockwork lithographed tinplate 0 gauge trains there as well. However, in 1929, it sold its New Jersey business to the A. C. Gilbert Company, whose similar Erector Set toy was popular in the United States, and Meccano's trains and construction sets disappeared from the U.S. market by 1930. In early 1934 Meccano Ltd introduced Dinky Toys, a new line of die-cast miniature model cars and trucks under the trade mark "Meccano Dinky Toys". In the same year, they also introduced a construction toy for younger children called Dinky Builder. It comprised rectangular and triangular hinged metal plates that could be quickly and easily assembled. The parts were painted jade green and salmon pink in an attempt to draw girls into the otherwise boys-only toy market. In 1938 Meccano Ltd launched the 00 gauge Hornby Dublo model railway system, comprising both clockwork and electric train sets. Production continued until 1964. In 1942 the production of all toys ceased due to wartime legislation and the company switched to manufacturing for the war effort. Despite the heavy bombing of Liverpool during the war, the Binns Road factory was not damaged. The production of Meccano, Dinky Toys and Hornby Dublo slowly resumed after the war in 1945, but was interrupted again in 1950 by the Korean War due to a shortage of metal. In 1960 Meccano Ltd purchased Bayko, a Bakelite building model construction toy, from Plimpton Engineering in Liverpool, and moved all its production to Meccano's factory in Speke, Liverpool. The construction sets were updated and polystyrene was used for all the plastic parts instead of Bakelite. Manufacture of Bayko continued until 1967. Meccano Ltd also manufactured Kemex (chemistry sets) and Elektron (electrical sets). Takeovers By the early 1960s Meccano Ltd began experiencing financial problems, in spite of exports worth over £1m, and was bought out by Lines Bros Ltd (tradename: "Tri-ang"), Meccano's biggest competitor, in February 1964. This purchase included both the British and French Meccano factories. Sweeping changes were implemented, including the removal from office of the last members of the Hornby family and applying
