I found a couple of Fairey flying boats but lost the link now.Wish I could be more specific. The history of the early days of Fairey Aviation seems a little obscure.
I don't think the flying boats need to be tri-motors. That must deserve a bonus.
My special book has a few Fairey floatplanes in it. Still can't find any Fairey flying boats though. It's not easy trying to find out about the companies early history but so far all early Fairey types have been relatively small aircraft (no more than three crew). Where as most flying boats were quite a lot larger.
