"Despite the scale and complexity of Merton, Lines Bros. Ltd. continued to acquire companies and premises around Britain and across the channel. They further extended the Unique and Unity Cycle Co factory in 1950, (later renamed Tri-ang Toys (Birmingham) Ltd.), and the following year took 100% of the share capital of Rovex Plastics Limited of Richmond, which was set up in 1946 by Alexander Venetzian and which produced electric train sets, mainly for Marks and Spencers. This was re-named Rovex Scale Models Ltd, and produced the Tri-ang electric model railway system. In 1954 it moved to a new factory in Margate, Kent, and the original Richmond facility was used as an overflow for Merton, housing Lines Bros. (Richmond) Ltd. and producing mainly musical toys, later becoming involved in the development of electronic toys................The following year, in November 1958, they bought Minimodels Ltd., a Havant company founded in 1947 which had introduced its Scalextric racing system in 1957......
The Hornby-Dublo range of train sets, which had been manufactured by Meccano, were consolidated with Tri-ang’s own railway system and sold to Rovex Scale Models, who continued production under the name Tri-ang Hornby Railways at their factory in Margate."
