602 Squadron claims 16 August 1940

[Peter Cook]

602 Squadron were involved in two combat actions on 16 August 1940, during the first, F/O Boyd claimed a Ju 87 at 13.05. The second series of combat took place between 16.55 and 17.10 during which claims were made for a He 111 by F/O Boyd and a Bf 110 by F/O Webb. These three claims are listed by John Foreman in RAF Fighter Command Claims, and by Simon Parry in the BOB Combat Archive. However, the 602 Squadron ORB Form 540 for 16 August states "17.10 – In these actions two Me 110’s were destroyed, one He 111 destroyed, two He 111’s probably destroyed and five Me 110’s destroyed." Does anyone know the source and the identity of the other pilots that made these additional ten claims?
In Zerstörer, Messerchmitt 110 and its Units in 1940, by John Vasco and Peter Cornwell, there is a section describing the loss of Lt Marchfelder's Bf 110 of Stab Ill./ZG 76 during the combat in question, with a quote from S/L Johnstone of 602 Squadron, who was the possible claimant, but I can't find a claim listing for Johnstone for this combat. Later in the text the authors also describe a possible claim by P/O Moody for the Bf 110 of Oblt Schlaffer, Staffelkapitän of 9./ZG 76. Again, I can't locate a claim listing for Moody. Any 602 Squadron historians out there?
