Lot 358: Singer 4ADT Roadster
The Singer Roadster was launched by the Singer Motor Company in 1939 as an open version of the Bantam saloon. Production was suspended for the duration of World War II following which production of the car was re-started in virtually unchanged form. It was upgraded to the 4A model in 1949 with a four speed manual gearbox. The short lived 4AB and 4AC models came in 1950 followed finally by the 4AD or SM roadster in 1951. The last cars were made in 1955. The Roadster was updated to the 4A model in 1949 by fitting the four speed gearbox from the Singer Hunter. A Solex carburetor replaced the SU used on the previous car. The 4AB received a new chassis with independent front suspension by coil springs. The engine remained unchanged but the brakes became a mixed hydraulic/rod system. The final version of the Roadster used the 48bhp, 1497cc engine from the SM1500 saloon fitted to a virtually unchanged chassis and body although the brakes were changed from pure mechanical to a hydraulic/mechanical hybrid system. Power was increased to 58bhp in 1953 by fitting twin carburetors to the engine. Although early production was still all for export, from 1953 cars became available on the domestic market. A car tested by The Motor magazine in 1951 had a top speed of 73mph and could accelerate from 0-60 mph in 23.6 seconds. This very rare 1954 lefthand drive Singer 4ADT, is one of the last of Singer roadster series, The T indicates that this has enhanced performance due to the twin carburettors fitted. In 2002 the Singers Owners club carried out a worldwide survey and found only 149 Singer 4AD's still existed of which only nine 4ADT's have survived. This car has just been imported from the United States of America, a prime, rust free restoration project. The vendor has informed us that the car is complete; the engine is free and hopes to be running by the time of the sale. We are also informed that it has matching numbers. The chassis appears to be in good order with the brightwork, reportedly, complete. It has been supplied here with all United Kingdom duties paid as well as the paper work necessary to register the car.
