Westland Wessex XS122

XS122 is ex-Fleet Air Arm Wessex that has ended its days in 26m of water at the National Diving and Activity Centre.

Last week the conditions in the quarry were very good indeed:-

Conditions are not always as clear…

I have posted over on PPRUNE, but I was wondering if anyone here might have information on this airframe? Contemporary photographs of XS122 in service would be of interest too.

Can anyone help?
