A special Pre-Qualifying session was held for 'local' South African drivers who had to lap the East London circuit in under 1'37", in order to be allowed to qualify for practice. Three drivers failed to do this.
The drivers in this session were (I think) those shown below, I have shown times recorded in official practice sessions. I am not 100% sure if all these drivers had to attend pre-qualifying session.
No 17: John Love (Cooper T55-Climax) 1'33.8" (qualified)
No 18: Paul Hawkins (Brabham BT11-Lotus) 1'33.1" (qualified)
No 19: David Prophet (Brabham BT10-Cosworth) 1'33.9" (qualified)
No 20: Piet de Klerk (Alfa Special) 1'33.3" (qualified)
No 21: Doug Serrurier (LDS-Climax) 1'35.7" (did not qualify)
No 22: Ernest Pieterse (Lotus 21-Climax) 1'37.9" (did not qualify)
No 23: Neville Lederie (Lotus 21-Climax) 1'35.2" (did not qualify)
No 24: Clive Puzey (Lotus 18-Climax) (did not pre-qualify)
No 25: Sam Tingle (LDS-Climax) 1'34.6" (qualified)
No 27: Brausch Niemann (Lotus 22-Ford) 1'36.2" (did not qualify)
No 28: Trevor Blokdyk (Cooper T59-Ford) 1'35.2" (did not qualify)
No 29: Jack Pretorius (LDS-Alfa-Romeo) (did not pre-qualify)
No 32: Dave Charlton (Lotus 20-Ford) (did not pre-qualify)
Has anyone seen the pre-qualifying times for the above drivers?
