capacity increased to and an additional crankshaft main bearing added (up from two to three). And, like the Junior and Six, the track was increased. One other model was a fabric-bodied convertible saloon, the Sun. The redesign left Singer with a few hundred older chassis, which the company bodied and sold as Deliverys, at £180. Toward the end of the year, a privateer ran a two-seat Junior up Porlock Hill one hundred times in fifteen hours, which moved Singer to rename that model the Porlock. In 1929, a 2+2 on the Junior chassis appeared, and the Senior disappeared, while the Six gained a sidevalve. This was joined by a Super Six, with a OHV and four-speed manual transmission. This was, said The Autocar, "the most impressive Singer yet" The Junior of 1931, with styling resembling the top-priced saloon and a "waterfall" grille, which lent the car its common name. The range continued in a very complex manner using developments of the ohc Junior engine, with an , the Ten, the sidevalve 12/6, the sidevalve 18/6 (now ), and the OHV Silent-Six (now ). At the top of the price range was the £480 Charles Frederick ‘C F’ Beauvais-designed Kaye Don saloon, built on the Silent-Six platform. Hydraulic brakes were standard, except for the Kaye Don, which relied on servo-boosted Dewandre brakes. A sliding sunshine roof was also available. In 1932, Leo J. Shorter became chief engineer (by 1940, technical director). He and two other designers created the new Sports Nine Sports, which made its debut at the London Motor Show that same year; it featured a two-bearing crankshaft engine of 972cc, which gave the car its name. Owing to manufacturing difficulties of the new bodywork, the "9" engine was fitted to a number of Junior chassis' as a stopgap until the production cars were ready, which gave rise to the incredibly rare "Junior-Nine". The production numbers are unknown, and only 8 are known to have survived. And in 1933, The Nine was joined by a new six-cylinder, a 1.5 Horsepower six-cylinder, and a 2-Liter six-cylinder, while the Junior was dropped and the new sidevalve-engined 12 displaced the Ten. The Sports Nine was "an immediate success" among trials racers, and Singer entered a specially-prepared version at Le Mans, which led to the Nine being commonly called the Le Mans. Singer earned an "excellent reputation" in racing before three works Nines appeared
