| Albert Milner (247 Levis), who finished second in the 250cc Class, came in at the last minute as a replacement for the ageing Bob Newey, who found his practice laps far too exhausting to contemplate 500 miles of actual racing. His Levis had a 60 X 70mm single-cylinder two-stroke engine of the type which Geoff Davison had done so well on in the Isle of Man TT Races. Capable of revving up to 5000rpm, it was of simple 3-port construction with a cylinder of composite manufacture consisting of a finned aluminium alloy jacket shrunk on to a cast iron liner. A cast-iron piston was also used and an external flywheel.
In fact, Milner had had one of the toughest rides of all in this race and was lucky to finish. After leading the 250cc Class in the early stages, his frame broke. He managed to lash it together and carried on, but top gear - it was a manual change - would not stay in. He solved this problem by jamming the lever in top with the tang of a file and at last got going again. Then, a few minutes later, when flat out down the Railway Straight he and his machine were hurled off the track by Freddie Dixon's riderless Harley-Davidson from which the latter had just departed. There were no injuries though and both machines survived, so after a few moments both riders were on their way again. The 350cc-Race-winning Ivy was also a two-stroke and had a bore and stroke of 75 X 79mm. Its engine had a one-piece crankshaft with shrunk-on rims and a light-alloy cylinder head. The drive was all-chain via a Moss gearbox with foot change. Parham's winning Coventry-Victor in the 750cc Class had a 688cc (75 X 78mm) horizontally opposed side valve flat-twin engine, set longitudinally in the frame. Cyril Pullin, the 1914 TT winner, finished fourth in the 1000cc Class at 59.69mph riding his self-tuned 996cc ohv Zenith-Anzani. Its V -twin engine had a bore and stroke of 83 x 92mm and four pushrod-operated valves per cylinder located vertically. Other fea�tures of this Hubert-Hagens-designed engine included a large finned oil reservoir and a mechanical oil pump driven from the timing gear. It was said to develop 24.5bhp at 3500rpm. Greatly impressed by Cyril Pullin's tuning abilities, Les Bailey, of the Douglas concern, his future brother-in-law, suggested he try his skill on a Douglas. This Cyril decided to do and was given one of the new 499cc ohv models, which he entered for the Ealing Club's meeting on Saturday, July 16th. [page 6] |
