I think you'll find some of the F4M had powered wing fold as well, I remember doing the runs for the riggers for the OOP code for the wing fold on 56(F) in the late 80s.
Lots of the 228OCU F4M's had powered wing folding too as they were part of the batch of aircraft ordered for the RN originally.
Used to be great fun going along the line to unfold/fold up to 25 jets wings on a Morning/Night. Got to do some cheeky little ground runs too all a Big Billy Bonus for a Sootie Liney
We also went around painting the Lock Indicator pin Dayglo Orange too after the Germany incident.
Happy days !
