I normally write my own descriptions of cars but having Googled Singer le Mans I came across the following uncredited description and my thanks go to whoever wrote it!
Origins of the Le Mans model
The Singer Nine - the Le Mans was an evolution of the popular Singer Nine which was a dependable and well-engineered sports car.
Le Mans 1933 - Singer entered a team of works-prepared Nine Sports models in the 1933 Le Mans 24 hours race.
Class Victory - the Nines performed well finishing 13th overall and winning their class which motivated the factory to release a model in 1934 named Le Mans
Engine Upgrades - the Le Mans featured a hotter camshaft, a large finned aluminium sump and a counter-balanced crankshaft for better high-rev performance.
Close-Ratio Gearbox - the engine was paired with a close-ratio gearbox for more effective racing and spirited driving.
Distinctive Styling - the new model had a faired-in scuttle and a slab fuel tank giving it a sporty appearance.
Performance - the Le Mans was praised for its ability to perform as a normal road car during the week and a competent competition car on the weekend.
Market Impact - the mounting successes at Le Mans showcased Singer's capabilities and increased the brand's popularity against rivals like MG and Riley.
Our Car - according to a buff card log book dated 26th October 1959 our car was first registered on 5th of January 1934 and its dashboard carries a plaque commemorating the Singer Nine’s 1933 class win.
There is a selection of pictures of it on the file recording a comprehensive body rebuild/restoration and the car us currently being checked over mechanically by a very experienced vintage/classic car engineer so the car will go as well as it looks.
We also have the car's Singer Owner’s Club Dating Certificate which records its first owner as R M Scott Brown of Kilmalcolm in Renfrewshire and it is perhaps reasonable to assume that he was related to Archie Scott Brown who was born in Paisley (also in Renfrewshire) which is 10 miles from Kilmalcolm.
Despite being physically disabled Archie went on be a very successful racing driver in the 1950s and you can read all about him on Wikipedia – it’s quite a story!
There is also an uncorroborated note on the file saying that R M Scott competed with this car in a team trial which was recorded in the Autocar Volume 72 part one.77
