Hi.
I do not know what your sources are, but there seems to be a bit of a problem to find these in the german records....
I think maybe the dates and data are a bit incorrect.
On November 11th 1943, the following loss were recorded by I./JG 11, and the location given as Langesund. JG 5 has not recorded losses of a Bf 109 on this date as far as I have been able to see.

Regarding the other date, the only loss I have been able to find that could match your given location would be this one:

Of course, the location Hamna isnt very distinct!
