Fairey Gannet wing folding

Thanks for your help, everybody. The tech sheets are just what I needed,

Described below:

I was on site at Newark Air Museum back in 1983 when their Gannet AEW3 was delivered & offloaded by MARTSU. The wings were unfolded using a handpump by different members of the delivery team.

As I recall this mechanism was located somewhere in the rear fuselage. 

I wrote an article on the move for FlyPast but I do not have a copy immediately available to see whether this procedure was mentioned.

I am sure the Gannet that was in the Historic Air Museum Southend wings were folded manually, how I know not but possibly a winder

I don’t know, but at an educated guess I would say an on-board hand-pump (and about 50,000 cycles) to fold the wings! This seems to be the preferred option for a back-up for most military hydraulic systems (from aircraft to 155mm howitzers).

Other options could include compressed-gas (nitrogen?) from on-board bottles although this is more usual for emergency lowering of undercarriage (and is probably a bit ‘all or nothing’ for the more delicate operation of wing-folding)?
