Perhaps I can help
Simon
I may have some information that might interest you. In the late 1980’s I co-produced a documentary for ITV called The Last Stringbag which featured LS326, then, the only airworthy Swordfish. I have the production file which contains names and contacts from the time, for example, a pamphlet called RNHS Engineering Team which includes the names of those serving at the time.
I could also let you have a DVD of the programme, which brought together many surviving wartime crew and construction workers including the last 3 crew from the channel dash.
Lt. Cmd. John Beattie flew the Swordfish, and Lt. John Baker carried out mock attacks in the Sea Fury for the film. There are a number of name contacts from that period of the Flight.
Please PM me if I can assist you at all.
Regards
John H.
