I remember the wing fold doings now. The FGR2 was in the main down to brute force ie two hairy ****** riggers would push the wing up to one very sticky footed rigger who would be leaning way out past a safe angle waiting to grab the tip and lift the whole thing past vertical. You have to appreciate that this operation, in fact the whole F4 thing, pre-dated the H&S at work Act. Lowering was the reverse, the most important aspect was to make sure that the sticky footed rigger's reach coincided with the hairy ****** riggers reach otherwise the wing would crash down with a horrendous thump (once "thumped down" on the Chief's head, but that's another story). To lock down you used a speedy to wind the mechanism over then "Excalibur" to wind in the little day-glo plug.
The matelots, and their FG1, didn't have the necessary ooomph and strength of wrist and instead relied on hydraulics.
