There are really two questions here :
1) Was chassis 701 the first Lotus 18? - most probably yes as it was the first chassis number allocated to a Lotus 18.
2) Was chassis 701 driven by Jim Clark? - not so sure as the first race for a Lotus 18 (presumably chassis 701) was on 26 December 1959 with Alan Stacey driving while Jim Clark didn't race a Lotus 18 FJ until 19 March 1960 and this (from photographs) was car #22 with alloy side panels so is probably chassis 703 being the car that subsequently went to Jim Palmer in New Zealand. Did Clark subsequently race chassis 701 in April or May 1960??
