Thanks scotsman. If you look at this thread, there is an old photo of the JB 242 (a bit down on site 1). http://milviz.com/forum/viewtopic.php?f=56&t=2569
It is difficult to see any outline on the black nose tip. As the photo is in B/W, it may be there (the red may be obscured by the grey background).
I have used illustrations as reference for this livery. I don't know how much I can trust these illustrations, but none of them shows the red outline.
As for the fox patch, it seems like the 2/JG 72 was painted like on my liveries.
So I think I will leave them just as they are now. If any adjustments, it will be minor corrections to the camouflage paint :icon_lol:
