Harry what a great photo. It seems the Sunderland/Sandringham that Kermit has in Florida is the same one that I saw and have a photo of. The Sunderland is a big secure looking flying boat. The Princess is an amazing design it is an airliner for sure with that fuselage and then with the hull of a boat stuck on the bottom. Might make a small model of it first something around 5- 6ft wingspan. Swaying towards the Princess in case you hadn't guessed.
