1931 ASTON MARTIN 1.5 L International

Chassis KO 84 – open tourer

Full Description

The “International” model was first introduced at 1929 London motor show.
Available in many configurations, it was mostly produced in the short chassis 2/4 seat arrangement as the “International Four seater sport” which provided the best performance overall as a simple and elegant performer.
A total of 129 International first series have been built up to 1932, most of them bodied by Enrico Bertelli Ltd, until Aston Martin Motors stopped the production in favor of the iconic “Le Mans” model.

John Cadbury acquired the Aston Martin International N°KO 84 in 1931 and participated to the Alpine Trial that took place in the Italian Alps in 1932.

An important documentation comes along with the vehicle as she had several owners after John Cadbury and went through several transformations. Equipped with a 2 liter AC engine, the original engine still exists and needs to be reassembled.

On sale in JWA Soft Auctions, starting from June 1st, 2021.

History

John Cadbury, first owner from 1931 to 1933

John Cadbury acquired the Aston Martin International KO 84 in 1931. He mentions himself his acquisition in a letter dated from May 24, 1970. At the same time, a document from the Country Borough Stockport states that the vehicle is the property of John Cadbury since March 19, 1931.

John Cadbury explains that he handed over his vehicle in January 1933 to a Birmingham dealer : “Patrick Motors Limited”. He does not know to whom the Aston Martin KO 84 was sold but says he saw it later in the streets of Birmingham (letter dated May 24, 1970).

In an undated letter, probably after 2003, Matthew Cadbury describes him as follows: “John was a quiet and shy man, but he loved motor cars and owned a series of Aston Martin”.

This photograph shows Mr John Cadbury driving his car during the test over the Stelvio pass.
The road, a great engineering achievement, reaches a height of over 3000 feet and is famous for its hair-pin bends.

During its long life, the vehicle has undergone various modifications.

The original engine (1.5 l) – which needs to be rebuilt – has been kept and can be reassembled on the vehicle to recover its 1931 condition.
It should also be noted that at that time, the color of the bodywork was black.

The Aston Martin International KO84 has been fully restored in the years 2009-2010 by JWA Classic.
Absolutely all parts were disassembled, cleaned, overhauled (or replaced) and reassembled.
