1952/1953

Chassis number 52/107

Hersham and Walton Motors (H.W.M.) was formed after WWII by the partnership of George Abecassis and John Heath. George was a well known Grand Prix racing driver and John a very competent engineer. They joined forces to produce sports and racing cars based on Geoffrey Taylor's ALTA engines, their own tubular chassis and proprietary motor components. They were ably supported by the famous racing mechanic Alf Francis. Following a successful prototype raced in 1949, a team of four offset single seaters were built for Formula 2 racing in 1950 and in 1951 this was followed by a true single seater. These cars were campaigned with some success by Sterling Moss, Lance Macklin and Peter Collins in Continental events, where British Racing Green was otherwise noticeably absent.

There was a new chassis for 1952 including 52/107 which was allocated to Lance Macklin as the H.W.M. number one team car (52-1). These cars were lighter and more rigid, with torsion bars supporting the De Dion, ZF differentials and inboard rear brakes. HWM took over the ALTA engine and with new components and Cylinder head porting increased power to some 140 bhp. The competition was stiffer and the cars were campaigned hard away from the UK workshops. Nevertheless there were good placings – Moss, Collins, Hamilton, Cantabous, Frere, Macklin, Claes,  all gaining places in International events. Claes won at Chimay, Frere the GP des Frontieres, Macklin the International Trophy and Moss Castle Coombe.

The budget did not run to new cars for 1953 but all chassis were modified and upgraded. In this form, now designated car no. 53-1, it was still largely driven by Lance Macklin who gained a 3^rd at Aix les Bains and a 4^th at Crystal Palace.

At the end of 1953, having competed in no less than 34 Grand Epreuve in two seasons, chassis no. 52/107 received special treatment in the form of the supercharged engine from Joe Kelly's Alta GP3, mated to the Jaguar C type gearbox. This car was given to Tony Gaze to take out to New Zealand and campaign in the Tasman series Formula Libre events, with a view to sale.

In its first outing, the NZ Grand Prix, it came 3^rd followed by a 2^nd in the Lady Wigram Trophy, beating Ken Wharton in the V16 BRM. It was then bought by John Horton, he and others who continued to campaign the car in International events, including the NZ and Australian Grand Prix until the mid 60's, by which time it was outclassed and fitted with a 3.8 liter Jaguar engine. The car has since been re-united with its original supercharged ALTA engine and returned to the UK for restoration. After this the car participated in prestigious historic racing events. As such the car has been owned and driven by the Chairman of the Historic Grand Prix Cars Association (HGPCA) and has been in his possession for the past 12 years.

H.W.M. never built another Grand Prix car and effectively ceased operation following John's death in 1956. George Abecassis wrote in 1980: “The supercharged HWM which went to New Zealand was undoubtedly the most exiting and fastest HWM we ever made.

This car is the most original and unique model of the H.W.M. marquee with an incredible detailed history of period photographs, articles and even mechanics notes. No expense has been spared on the restoration and maintenance as evidenced by the files of invoices. A rare opportunity to obtain a unique part of the British GP racing history.
