In the video, Carter states that he brought the aircraft down in the Ypres - Comines Canal, which places it in Belgium. The rudder is of the sort used by the Albatros D.III (OAW), Albatros D.V, and Albatros D.Va.
A.W. "Nick" Carter shot down some Albatros D.III's, but they were much further to the south, in France. He was credited with 6 Albatros D.Vs, 5 in Belgium and 1 in the far north of France.
The dates of these victories are:
July 17, 23, 24, and 27 in 1917 and February 19 and May 8, 1918.
Jasta 11 suffered no losses on these dates.
The paint scheme on the rudder would be highly unconventional. It has a real Hollywood look to it. I suspect it was repainted at 10 Naval Squadron prior to it being used as a mess decoration.
I'm very happy you gave us the link to that video. In addition to WW1 pilots
Raymond Collishaw,
Mel Alexander, and Nick Carter, it featured Stewart K. Taylor, the top Canadian WW1 aviation historian. He's the soft-spoken fellow in the yellow shirt with black tie.
Stewart Taylor is an old friend of mine. He's still alive at age 88. I originally met him in 1984 at an RFC/RNAS/RAF reunion in Winnipeg. The 1985-87 reunions took place at Ottawa, Calgary, and then finally in Ottawa again. It was a real surprise to see him in this Raymond Collishaw documentary. I'll have to mention it to him.
I suspect it was Stewart's place where the interview with him and one of the snippets with Collishaw took place. I visited one of his houses, in Don Mills, a sort of suburb of Toronto, but the interior looked quite different.
I also met Mel Alexander at those reunions, and recorded an interview with him.
