Tony Marsh working his 1960 BRM P48 chassis ‘484’, 2.5 litre ex-Bonnier 1960 F1 car very hard, lifting an inside rear wheel into ‘The Courtyard’, Bo’ness Hillclimb, Scotland 1966…

Two of the reasons why the content of this blog is eclectic are that it suits my broad racing interests and that a photo is usually the inspiration for an article, this shot is one of those! I tripped over it on ‘The Nostalgia Forum’, which is a wonderful place for those of you who may not paid it a visit. You can get lost in there for weeks! http://forums.autosport.com/forum/10-the-nostalgia-forum/

Lots of ex-GP cars have found their way into British Hillclimbing over the years and Tony Marshs’ BRM P48 is one of those…

The old and new…P25 and mid-engined P48 prototype ‘481’ on test, circuit unknown, August 1959 (Unattributed)

The 1951 BRM P15 supercharged 1.5litre V16 racer was a disaster, too complex, too late, a fabulous bit of kit and the greatest sound in motor racing full-stop. Aural orgasm is not going too far to describe its musical, mechanical, sonorous howl!

The design which followed was the reverse, a simple 2.5 litre, DOHC, Weber carbed’, front-engined, space-frame chassis car which served BRM from 1955 to 1959, finally achieving a breakthrough win for Bourne in the 1959 Dutch Grand Prix. Jo Bonnier the driver.

But the game had moved on, Cooper dominated with their Coventry Climax engined, simple mid-engined cars. Jack Brabham took the title in 1959 and 1960, Tony Rudd and his team needed to respond.

BRM were famous for their engineering process and toolroom quality but the P48 was a ‘quick fix’, utilising as many of the P25 components as possible. In essence the P48 was a mid-engined variant of the P25, right down to its controversial, less than reliable ‘cookie-cutter’, single, gearbox mounted rear disc brake.

The ‘prototype’ chassis ‘481’ BRM P48 was tested in practice at the 1959 Italian Grand Prix, in September by both Harry Schell and Jo Bonnier. They stayed on at Monza for further testing. The P48 was then developed over the Winter of 1959/60 and made its race debut at Silverstone early in 1960. (John Ross Motor Racing Archive)

1960 was the last year of the 2.5 litre Formula, the P48 Mk II was more competitive than the first iterations and devoid of the ‘cookie cutter’ formed the basis of BRM’s 1961 contender.

This car, the P57 was Coventry Climax 1.5 litre FPF powered until BRM’s fabulous and successful P56 1.5 litre V8 was developed. See https://primotipo.com/2014/10/12/graham-hill-brm-p57-german-gp-1962/

The P48 evolved into the P57 delivering BRM’s first and only Manufacturers and Drivers Championships in 1962.

Graham Hills’ P48 ‘485’ took 3rd place in the 1960 Belgian GP at Spa won by Brabhams’ Cooper T53 Climax. The weekend was one of GP Racings’ worst, Moss broke both legs after an axle failure, Mike Taylors’ steering failed, he crashed into trees dying of his injuries several days later. Both were driving Lotus 18’s, the accidents in practice. In the race Chris Bristow crashed his Cooper at Malmedy, pushing too hard and was killed, and Alan Stacey was hit in the face by a bird near Masta, also crashing and dying instantly. (Unattributed)

Tony Marsh…

Marsh was an iconic hillclimber, first taking the British Title in a Cooper Mk8 Jap in 1955, after two more successive wins he turned to circuit racing winning the British F2 Championship in 1957 with a Cooper T43 Climax.

He also competed in his private Cooper in the 1957 German GP, finishing fifteenth in his F2 car and eighth in 1958 in a Cooper T45 Climax.

Marsh raced a private Lotus 18 Climax and his own BRM P48/57 1.5 V8 engined car in 1962, in some Non-Championship F1 events. Best placings were 4th in the Pau GP and 7th in the International Trophy at Silverstone.

He returned to hillclimbing in the mid-sixties winning the championship a further three times and was competing right up until the time of his death at 77 years of age in May 2009.

Bo’ness Hillclimb…

Bo’ness is 17 miles north-west of Edinburgh, the hillclimb used from 1934 to 1966 ran through the grounds of Kinneil House. James Watt of steam engine fame lived there, the grounds contain the ruins of his cottage and the boiler of his ‘Newcomen Engine’.

Tony Marsh set the record for the climb in June 1963, a record which stood for all time, the last meeting in June 1966. Revival meetings have been held in recent years.

Some former motor racing greats held the climbs’ record including Bob Gerard, Ken Wharton, Ron Flockhart and Jim Clark, early in his career with a Lister Jaguar in 1959.

    Great photo of Dan Gurney at Silverstone in 1960 – is he wearing a pair of business shoes?
