This very special Alfa Romeo left the Milan Works in December of 1929, having been ordered that October by Mr. Leonard Tweedale. Tweedale was part of a wealthy family of industrial machinery makers in the North of England and passed the car on to his son, John, a couple of years later as a birthday gift. The car’s history file contains a delightful photograph of father & son with the car, believed to be at said 21st birthday party, celebrated in Scotland.

After a year or so John Tweedale sold his Alfa Romeo in a private deal to David Brown. Later on in his life David Brown would take ownership of Aston Martin Motor Cars. Tweedale would go on to have some success rallying and trialling a Frazer Nash. After a short time, business commitments saw Brown sell the car back to Stiles at Alfa Romeo British Sales.

In 1933 while thought to still be in the ownership of David Brown, the Alfa was lent to well known motoring personality J A M Patrick who competed in VR 4659 at Shelshey Walsh, achieving 3rd in class (See photograph). The car was subsequently sold to well known sports car dealer J.H. Bartlett of Notting Hill Gate.

The car was then subject of an extensive article in Autocar magazine’s ‘Talking of Sportscars’ series, dated April 1st 1949 (copy on file). The author, one ‘G.C.D’, purchased the car during WWII. As can be seen in the copy of the magazine held in the history file, the car is given a glowing review. “In my hands the car has now covered well over 15,000 miles on the road without being touched”….“the most reliable car I have ever owned”….“It seems quite impossible to go into a corner too fast provided all tyres have equal amount of tread… it is perfectly simple to take corners with a controlled four wheel slide.”

The buff logbook records the date of original registration as 9th January 1930 and shows ownership from 1957 onward. This document shows the chain of ownership up until 1965 when the previous owner, Robin Toone, who acquired the car from John Le Sage with whom he was attending university. Dr. Toone went on to compete extensively with the car in VSCC events over the next 50 years. In an amazing pair of ‘twists of fate’ (documented in the history file) it later emerged that Robin Toone’s father had been Tweedale Jr.’s flying instructor in WWII, whilst Tweedale’s post-war home in Northamptonshire later became an old people’s residence where Robin Toone’s mother lived out her later years!

In 2015 the Alfa was acquired by the current owner. The car was in good running, driving condition but was in need of some restoration after five decades of predominantly competition use. The decision was taken to carry out a complete but sympathetic cosmetic restoration, whilst taking great care to replace as little of the original structure as possible. On close inspection, whilst being dismantled, it was evident how original the car was. ( please request photos of numbers)

Presented in lovely condition and ready to be used, this 1928 Alfa Romeo has a tremendously well documented history. Recently this 1929 Alfa Romeo 6C 1750 SS has been accepted onto the Registro 1000 Miglia making it an easy entry for the 2024 edition of the 1000 Miglia event.
