Car Of The Month

346 Dutch

1955 346 Sapphire MkII Auto

This Sapphire MKII auto, original reg. number UTV 563, started life in 1955 with a Mrs Constance Prior, married to Mr Ben England, general manager of Nottingham Public Transport. It got bucket seats mounted two inches backwards and an extra two inches lower cushion, obviously to deal with the length of Mr. England. In 1970 it was sold to its next custodian who won several prizes with this car. In 1976 a Dutch owner bought the car at an auction by Christie's in the Netherlands. Subsequently, the car only covered an incredible 237 miles over the next ten years. In 1986 the car changed hands again. The new owner carried out a lot of work on the engine which he had revised twice, since the first revision didn't comply with his expectations. He converted it into a twin carburetor type using Star parts, which didn't really add to the fuel economy but it runs perfectly. He traveled all over Europe as far as eastern Poland and John O'Groats. Actually being a dedicated Rover P4 owner (the same car from 1970 on) I didn't plan to get hold of an Armstrong Siddeley. But when I learned that the previous owner was in his last days and being astonished by the excellent condition of this unrestored car, I decided to take care of it for the years to come. I received most comprehensive documentation, including Mr England's correspondence with AS and Rolls Royce concerning repairs and hupcaps lost. In the meantime I have the instrument panel brought back to its original lustre, replaced the pot scrubber air filters by washable K&S cotton filters, got the jerk-a-matic decently shifting and added a SU electric fuel pump near the petrol tank in order to have an instant starter after a few weeks rest. I further replaced the noisy stainless steel exhaust system with a system from the stores, well made but still not as silent as I would like. Still some interesting work to do.
