Leendert,
Yes, like that. I have seen this picture before but never had information that it was original. And your statement that FR886 was one of the ones delivered to the RAF as Piper Cub Mk 1 is the first indication of British Cubs I have read other than Ken Wakefield's statement that 10 L-4s were delivered to the British. Do you have any other info on what happened to the Mk1 Cubs?
In fact I had a Piper Cub in the 1970s that I painted in British markings without doing any detailed research. I did it because I wanted a Cub that wasn't yellow, and as a kid, I had been interested in the RAF and RCAF, and my flying instructors in the 1960s had been RAF/RCAF WWII veterans.
I figured if I painted my Cub in those colors I could pretend it was a Spitfire.
Cheers
Kerry
