Had a look and can't find much of any information. Fi-156 in North Africa with Rommel, very nice looking scheme in my opinion but would love to know the squadron codes if anyone miraculously has that information.
There is a picture of a Storch in this book by AAndrew Arthy
with the EXACT same camo pattern down to the shape of the green blotches. There is a white theatre band on the rear fuselage and the codes is CB+VZ in black. On the starboard side the letters CB are within the white band.
Wow that's perfect, reading through both books now. Thanks for the information on the aircraft and pointing me in the direction of a subject I had no idea about
