NAGr.12 :: 08/08/1944 :: losses

[Schenck]

I didn't even realize my question is related to an event occurred on the same date some years ago.
W/O Potvin of No 73 Sqn RAF claimed two Bf 109s shot down in quick succession while flying patrol at 23000 ft over Vis Island 1944. Both claims were certified. I've seen a report from LRDG that two enemy aircraft were shot down by Allied aircraft and crashed on Brac Island and Hvar Island each and I am not sure if this was a source of confirmation.
According to ULTRA, 2./NAGr.12 lost one G-8 while on recce Termoli - Gargano - Pescara and August summary gives only one loss owing to an enemy action (2.Staffel) while Stab didn't suffer any losses (M.Holm gives one loss owing to other causes). So the question is, one or two Bf 109s lost, and I would appreciate if somebody knows the name of the pilot? Confirmed loss was W.Nr.200302. Thank you very much.
