Hi Stefaan,
don't forget, there is a difference between 2. and II.
Your plane was from the 2./JG 26, that was a part of the I./JG 26.
Btw, was it lost as "red 2" or as "black 2"? Is there something written in the report at the UK? On Peters photo is looks a bit like a red number with black border?!
Here it looks just black:

And at the museum, you know it Stefaan :-), it is a "red 2".
