From the Jasta 8 log compiled by Rick Duiven, Uffz Matthias Meinberg made his claim at 16:45 over Menin while Vzfw
Rudolf Francke made his claim at 16:50 over "Pembrouck".
Meinberg's claim probably reflects the loss of 70 Sqn's Strutter A1012, 2nd Lt R M Niel & Lt F W Harley, both KIA - their machine was last seen near Menin.
According to AIR1/848/204/5/385 (Reports on aeroplane and personnel casualties 1-14 June 1917), A981 was last seen near Menin on a photographic reconnaissance mission; according to AIR1/968/204/5/1100 (pilot and observer casualties, RFC France, 1 June 1917 - 28 February 1918) A981 fell at Rolleghem (some 12 Km south-east of Menin).
I have yet to positively identify "Pembrouck" but since A981 was the only other Strutter lost at about this time, it seems reasonable to link Francke's claim with the loss of this machine.
