Welcome to the Armstrong Siddeley Owners Club

Car Of The Month

1934 Short 15hp 6 light coachbuilt saloon

COTM April

15hp cars were built between 1927 and 1934 and were unusual for Armstrong Siddeley in having a side valve engine which was popular at the time. The engines varied in detail throughout the production run but all had a capacity of around 1900cc. Again unusual for AS, the earlier cars had a "flat" radiator grill but with the major redesign in 1931 the normal "V" shaped grill was reinstated. There were two chassis lengths and various body styles with some cars having bodies built by specialist outside coachbuilders such as Maltby, Salmons Tickford, and Mulliner. In all some 9458 15hp cars were built with the highest production figures in 1929 when 3653 15hp cars left the factory. The club knows of just 71 cars remaining worldwide but others may still come to light.
This particular model WH5477 was one of the last built, leaving the factory in May 1934, and has only had 11 owners in its 82 years. It is now owned by a club member who bought the car part restored and who has beautifully finished the restoration and returned it to its original condition. The restoration entailed the remanufacture of many parts and a complete engine rebuild.

Interestingly, despite spending many years all over the UK, it is now kept just 5 miles from its original 1934 registered address. The current owner has a long history file on the car which contains photos of it being used as a wedding car and also at some point being reclaimed by a former owner having been the subject of a bad debt! A stunning car.
