Welcome to the Armstrong Siddeley Owners Club

Car Of The Month

1956 Sapphire 346 Mk 2

346Mk2The Mk2 version of the Sapphire 346 was introduced in August 1954 and had several improvements from the earlier version, notably the braking system was improved by increasing the drum diameters and adding a Clayton Dewandre servo system. Also flashing indicators were added and an improved dashboard layout was installed. A fully automatic gearbox also became available adding to the choice of manual or pre select. 3724 Mk1 versions were built between 1952 and 1954 and 3956 Mk2 versions left the factory between 1954 and 1958.

This particular example was first delivered in July 1956 to a British Forces Lt Col in Cyprus. The current owner purchased it from a garage south of Munich in 1997. He has spent much time and effort in improving the car year by year, including adding twin carbs and Armstrong Siddeley power steering. The original colour was Sapphire Blue wth Champagne interior.
