Pretty sure that's not the FAA book I saw recently; at Tangmere we have a large collection ( over 5000 books, available for the public to view but not usually take away) - I'm hoping to be back maybe tomorrow -Thursday - so will look it up, it has a fair bit of detail.
Meanwhile, have you tried Yeovilton ( the curator side of course )- the Chief Engineer there, whose name I'm ashamed to say I've lost at the moment, is very knowledgable & helpful.
Our curator at Tangmere, David Coxun, knows the airfield & relevant squadrons & operations inside out, no harm in my asking him, but I suspect Swordfish are a bit outside his remit.
As I say I'll look up the book ASAP.
