[LQ-D_ND587]

Hmm......thanks...hadn't thought about this before...you have listed nine aircraft officially destroyed. Maybe over-simplified logic, but the OKL list (per Steve Wood) has ten claims so that corresponds with the info I had that both Marstaller and Beyer claimed and were awarded LQ-D of 405 Sqdn.

Including the shared victory, again according to the OKL list, Beyer claimed (and I understand was confirmed with) four 4 engined aircraft on May 8/9. The LQ-D claim stands out because of the altitude, Marstaller and Beyer both said they made contact above 7000 meters at the same grid reference. The puzzle here is the inconsistency with the CR from the Mosquito crew -- their 'contact' with Marstaller's Bf110 (and Lancaster LQ-D since they were already in contact) was at approx 4000 feet -- maybe at the bottom of a long corkscrew? However the CR also talks about the Mosquito crew observing three 'Halifax's' from a higher altitude before the engagement.

I need to try to figure this out some more....

I'm going to plot the interception point (from OKL) and the crash site (from your list) and try to 'connect' Beyer with the two unattributed lost aircraft from your list.
