: I am sure that Turner enthusiasts will be interested to know that when we took the 2 litre Connaught engine out of the Clairmonte Special and delivered it to Beaufort Restoration at Sittingbourne in Kent, they stripped it and gave us the following news.
: The crankcase is not the same as all the other Connaught engines they have worked on, and has cast into the bottom the initials JHT. This makes them believe that the engine was in fact a Turner engine, even though it has Connaught rocker covers. Both engines were based on the Lea Francis engine and are very similar. Jack Turner used a twin plug per cylinder aluminium alloy head which we still have, although we are told that it never ran reliably with it fitted, and that the cast iron Connaught head was more succeesful.
: The only other engine I have seen like this is the Turner 2 litre engine in the Turner F2 car now in the Sparkford museum.
