The photo is part of a whole sequence of 137 Sqn photos taken at Manston in 1943; the last Whirlwind ops for 137 occurred on 21 June 1943, when 137 stood down to re-equip with Typhoons.The remaining Whirlwinds were transferred to 263 Sqn which had its last op in December before re-equipping with Typhoons.

Hi NZtyphoon,

Thanks for the info on the book and the photograph. I’ll get the book. That sure is a nice photo! Unfortunately, I forget where I got it.

Following on the discussion about consumption and the use of 100 octane in the Blenheim, it shouldn’t be overlooked that the Defiant also used 100 octane and +12 boost. See the
Combat Report of T. D. Welsh of 264 Squadron from 29 May 1940 where he recorded "I pulled the boost cut out…" for example.

A.&A.E.E. reported on trials of the Defiant operating +12 boost.


And last but not least see Dowding’s memo from 1st August, 1940, with copies to all Stations and Squadrons, regarding Handling of Merlin in Hurricane, Spitfire and Defiant Aircraft wherein he mentions "The use of the automatic boost cut out control enables the pilot to get an emergency boost of + 12 lbs. per sq.in. from the engine for 5 minutes when circumstances demand it. Some pilots "pull the plug" with little excuse on every occasion."
