Note this picture- the fin detail on the largest on the right. You can see the hollow square detail that you request.The hollow is not vey deep though.


Zavod44-
Do these help you?
These were on display at the Brussels Air Museum.
They look pretty much original.
Noteworthy is the white stencil on one of the tail fins in the last picture.
I don't know whether the stencil is original or not?
Perhaps someone else may have a wartime photograph which can confirm whether this detail was present or not?
