thank you for the background Simon,I have been using an led lantern for light painting and getting good results. Nearest I got to any aircraft underwater was a cockpit in Stoney cove and that was back in the days when a deeper dive meant a twinset,no trimix or re breathers.

The give and take regarding exchanging information on this forum has always been part of the attraction. It is very far removed from an ebay listing and discussing sales and auctions helps many fill in gaps in collections and restorations. I cannot see any downside to mentioning sales and feel there is plenty of room here .
This particular collection looks wonderful and as many of us know the enthusiast of this type has saved much from being scrapped or just discarded.

have a look at issue two of this magazine https://www.afterthebattle.com/magazine/issues1-25.html

However in this case the team of volunteers have worked miracles to keep the project going and clocked up thousands of air miles flying from the Uk. Jokes aside I cannot think of amore dedicated group.

No proof of a Catalina in loch Ness which is local to me, a Hurricane was recovered from another loch in the Great Glen.Rumours of a Fleet Air Arm aircraft in an unnamed Loch north of inverness. RAF Coltishall sub aqua club did the Fritton lake P47 recovery ,i knew the chief diver and feel that they lifted all that was found.

Are you planning a trip to Scotland this year? Still wondering if a dig at Kinloss is on your list? I can can take you to the location on the base but we would need to ask ahead.
