David,
It is captured Dr.I 147/17 of Jasta 10, piloted by Ltn. Ludwig Keseling that we see being walked along the road by British troops...sorry but it had a RED rudder. Keseling was previously with Jasta 11, thus the RED cowling, wheel covers, aft fuselage and tail, but he transferred to Jasta 10 apparently with his Dr.I 147/17 still being in traditional Jasta 11 RED colors when he was shot down on March 24, 1918 near Morieul by anti-aircraft fire while attacking an observation balloon, and was thus bestowed with the British capture "G158" designation.
This original and existing YELLOW Dr.I rudder was donated by Captain/Major E. David, RFC. I too wonder which Dr.I it might have originally belonged to??????? Perhaps it could be
LVR's yellow Dr.I 454/17 rudder taken after his nasty crash on March 13, 1918 as a grim injury souvenir, then given away after the war to someone of importance? Hummmm...
...Perhaps a new thread is indeed warranted now, sorry Jeff.
Regards, Gary Sewall
