Lotus 59 & 69

[Chris Townsend]

Matter of time I suppose, but we've not had much discussion of this staple of early 70s F3 and Atlantic.

Can someone help me with information about the Lotus 69 and the difference between the 1970 and 71 models [designated 71/69 on the chassis plate]. First question is was the 1970 model a space-frame and the 71 model something else – I presume a plated space-frame rather than a monocoque.

I’m trying to work out the histories of Lotus 69s in Atlantic and FB [not helped by many 59s used in the formula being updated to 69 spec. My chief interest at the moment is in Ian Mawby’s cars used in Britain.

In 1972 Mawby uses an ex Wisell 1971 car which was built to F.B spec but used in F2, [71/69.FB.8] but at a Libre race at Brands in November he ‘writes off’ the car at the start. However the following week he’s back for another Libre race. In MN 14.12.72 Mawby says that he won in ‘the ex Wisell spaceframe that he completed after his start line shunt the previous weekend’. Given that he is talking about a replacement car, which is also ‘ex Wisell’, are we talking about him using another Wisell car rather than his 1971 model?
Funnily enough this was available for him because Stephen Choularton had used in Atlantic in 1972 Wisell’s first 1971 car [69.F2.1] [described as ex Fittipaldi – who used it in 1970 – and Pau winner, Wisell 1971 – and had it for sale from mid October 1972. This would be the earlier type of the car, and presumably a spaceframe where the other wasn't [exactly...]

Which ever car it is Mawby has another really big accident at Snetterton in 73 and the remains were sold to John Bicht who used them as the basis of his Swift [perhaps John can confirm this] and eventually taken to the USA.

Reminiscences, observations, complete Lotus build records all appreciated.
