I read a lot about the red baron, and as far as I know he flew 2 different Albatross 2 seaters over Verdun. I know for sure that Jasta 2 only had one seaters, 2 Fokker DIII and 1 Albatross DI from the 1st of September 1916, followed by a more Albatross DI and DII.
The LFG Roland CII reached the front in may 1916 over Verdun, giving us a possible window of 4 months but in the pictures I seen from the time he have an Albatross. But I know that Von Richtofen flew a Roland DII for 2 months after his Albatross DIII almost losts its wings during a dive in early 1917. The Roland DII is however a very different plane with no observer, it look very different from the CII..
There is of course the possibility that the Roland was piloted by Lothar von Richtofen, Manfreds brother who also was one of the top scoring aces... He also had a cousin in the war but he didn't start to fly until later.
Anyone know, or could post a picture of an Roland CII with a Richtofen in or next to? Did he flew one for a short time or did someone messed up and mixed up the Roland CII and DII (and in that case, how did they knew how to paint the plane?).
