SL100/4 is now owned by Christer Lofstrom and it residesin Sweden.
The following information comes from the excellent OldRacingCars.com:
Believed to be the works Lola T100 entered by Lola Racing for John Surtees to drive in Formula 2 at the start of 1967. Fitted with a Cosworth FVA engine and raced by Surtees at Snetterton and Silverstone in March 1967, then by Chris Irwin at the Nürburgring in April. Sold in May to David Bridges for Brian Redman to drive in F2 for the rest of that season. Retained by Bridges for F2 in 1968, when it was driven by Redman, Chris Williams, Mike Beckwith, David Hobbs and Robin Widdows.
Sold to Robin Darlington (Ruaben, Wales) late 1969, and used in libre racing in 1970. He advertised it in January 1971 when it had a twin cam and was prepared for the new 1971 Formula Atlantic category. Robin cannot recall where it went, but it was next seen in Sprints in late 1973, when it was driven by Richard Lester (Yoxall, Staffordshire). The car was run by Lester in the 1600cc class in Sprints and occasional hillclimbs from 1974 to 1977. Lester then acquired a March 73B, and advertised the T100 in January 1978 as "ex-Redman" with an all-steel twin cam and Hewland FT200 gearbox. This is likely to be the red/white 1600cc Lola T100 that Kenneth Brill (Redditch, Worcestershire) raced in libre at Croft in 1978. Subsequent history unknown.
Driven by: John Surtees, Chris Irwin, Chris Williams, Brian Redman, Mike Beckwith, David Hobbs, Robin Widdows, Robin Darlington, Richard Lester and Kenneth Brill. First race: Snetterton (R1), 24 Mar 1967. Total of 45 recorded races.
