Don, all sorts post here asking for help and its polite to add connected items, its not always clear what a person has seen and how something could be of use. It is also easy for the original poster to sort out what they need and if they hit gold then fine. Otherwise no harm done and better to respond than assume that they have already seen everything. As for the actual content being not reliable well thats a sweeping comment, many on line or book published accounts have parts which are in error and thats where a good research writer knows to check sources if not given. I collect lots of items of aviation interest but not grips….

I suggest also a copy of this magazine could be useful…

Cockpit mock-ups made by Prague’s BMZ Air Service supplemented the real Spitfires, only two of which were used in the film. Multiple-Spitfire aerial sequences were either out-takes from Battle of Britain or were cleverly computer-generated. …….EP120 and MV154 flew. Adding to poss confusion is that MH434 flew with Czech pilots in ww2.

Salvage took place in many of the sheltered sites in regards to flying boats despite listings of losses. In the case of two off Invergordon they were demolished by explosives as they were obstructing a shipping channel. The sites of large ships and aircraft inland and inshore have been found and picked over.Well thats my view from looking at reports over the last 40 years. https://blogs.wessexarch.co.uk/aircraftcrashsitesatsea/about-the-project/
