G & R Wrenn

G & R Wrenn was a British toy company specializing in model railways and associated hobby products. Founded in 1950 by George and Richard Wrenn, the business initially concentrated on trackwork for 00-gauge model railway equipment. Its early range included points and crossings designed for both two-rail and three-rail layouts, placing the company within the growing postwar British model-railway market. The enterprise began at Lee Green in southeast London and moved in 1955 to larger premises in Basildon, Essex. In October 1957, the family partnership was incorporated as G&R Wrenn Ltd. The company diversified in 1960 with Formula 152, an electric slot-car racing system using 1/52 scale. The system was smaller than the 1/32-scale format used by Scalextric and was designed to allow relatively extensive circuits on an 8-by-4-foot baseboard. Its distinctive track arrangement used twin conductor rails on each side of the slot, allowing three cars to operate on each lane. Early cars used an electromagnetic ratchet-and-pawl mechanism and contact breaker rather than a conventional wound motor. The resulting on-or-off control and sensitivity to electrical contact gave the cars a distinctive driving feel, but also contributed to reliability and overheating problems. Later versions adopted more conventional direct-current motors and variable-speed control. The range included models such as Ferrari, Cooper, Vanwall, Maserati, BRM, and Porsche cars, together with barriers, lap counters, pit buildings, and other accessories. Wrenn also organized a short-lived 152 Drivers club and produced a newsletter. The wider British model trade experienced serious pressure during the 1960s. Lines Bros, the company behind Tri-ang, acquired the Hornby Dublo range in 1964 and took a controlling interest in G&R Wrenn roughly a year and a half later. Wrenn obtained the Hornby Dublo tooling and began producing models from it under the Wrenn name from 1967, while also distributing remaining Dublo stocks. The Formula 152 slot-car system disappeared around this period, and Wrenn subsequently became closely associated with railway products rather than racing toys. In 1968, it also handled remaining stocks from Tri-ang's abandoned TT-scale range, marketed as Wrenn Table Top. From late 1969, products were styled Tri-ang Wrenn, although that presentation lasted less than three years. When the Lines Bros group entered receivership in 1971, Wrenn bought itself free from the Official Receiver and continued as G&R Wrenn Ltd. It retained tooling and rights for many former Hornby Dublo models but did not acquire the Hornby brand name. The company continued producing mainly die-cast railway models and also resold Lima N-gauge products in the United Kingdom under the Wrenn Micro-models name. During the 1980s it expanded beyond inherited designs with new products including air-smoothed Bulleid Pacific locomotives, commonly called Spam Cans, LMS Royal Scot models, and Brighton Belle train sets. The Basildon operation closed in 1992. Dapol acquired remaining materials during the closure, made limited use of some Wrenn assets, and incorporated certain designs into later N-gauge production. In 2001, Dapol sold the Wrenn company to three Wrenn collectors. The new owners established a Collectors Club and a website-based operation offering new models, parts, and spares. A 2009 hot-metal production run revived the popular Bulleid Spam Can locomotive body, alongside rebuilt Bulleid bodies made available to collectors. The company ultimately ceased trading in October 2015. G & R Wrenn remains significant among British model-railway collectors because of its continuity with Hornby Dublo tooling, its distinctive products, and the later collector-led effort to preserve the Wrenn name and parts supply.

G & R Wrenn began in 1950 as a partnership founded by George and Richard Wrenn. Its first products were 00-gauge railway track components, including points and crossings for both two-rail and three-rail systems. The firm initially operated from Lee Green in southeast London before moving to larger premises in Basildon, Essex, in 1955. The partnership became G&R Wrenn Ltd in October 1957. In 1960, Wrenn entered the electric slot-car field with Formula 152. The system used 1/52-scale cars and a track design with twin conductors on each side of the slot, permitting three cars per lane. Its small scale made large circuits possible on a standard 8-by-4-foot baseboard. Early cars used electromagnetic vibrator mechanisms and contact breakers, while later versions adopted more conventional variable-speed DC motors. The range was supported by circuit accessories and a short-lived 152 Drivers club, but the unusual scale and electrical limitations prevented it from becoming a major competitor to Scalextric. Wrenn also sold battery-powered boats. The company became involved with Tri-ang during the upheaval in the British model trade. Lines Bros acquired Hornby Dublo after Meccano Ltd collapsed in 1964 and later took a controlling share in Wrenn. Wrenn received the former Hornby Dublo moulds and began producing models from them under its own name in 1967. It also distributed unsold Dublo products. In 1968, Wrenn handled remaining stocks from Tri-ang's discontinued TT-scale range under the Wrenn Table Top name. From late 1969, products were styled Tri-ang Wrenn for a limited period. The Formula 152 system disappeared around this time. Lines Bros collapsed into receivership in 1971. Wrenn bought itself free from the Official Receiver and continued independently as G&R Wrenn Ltd. It retained much of the Hornby Dublo tooling and rights to produce associated models, but not the Hornby brand name. The company also resold Lima N-gauge products in Britain as Wrenn Micro-models. Its principal business remained model railway production, especially die-cast locomotives and rolling stock derived from the Dublo tradition. During the 1980s, Wrenn added new designs to its inherited range. These included air-smoothed Bulleid Pacific locomotives known as Spam Cans, LMS Royal Scot models, and Brighton Belle sets. The Basildon company closed in 1992. Dapol acquired remaining materials during the closure, used only part of the inherited Wrenn material, and incorporated some wagon and N-gauge designs into its own production. In 2001, Dapol sold the Wrenn company to three collectors. The new owners maintained the name through a Collectors Club and a website-based sales operation offering models, parts, and spares. In 2009 they arranged a hot-metal production run of the Bulleid Spam Can body and offered related rebuilt Bulleid bodies to collectors. The company ceased trading in October 2015. Its historical importance lies in its role as a British specialist model-railway maker, its stewardship of Hornby Dublo-related tooling, and its later preservation by enthusiasts.
