Caudron RAF 1915-16 and Farman at RDutch Navy

In a recent book a read (Military Airfield History / Sealand) are two photos
of Caudrons used and build(?) at Sealand / Mr. Duttons Flight School.
There are speciefied as Caudron Warped Wing Type.

What Type of Caudron is it? Type F or Type G.
Has those been produced in England by licence?


In a book about the Marineluchtvaart in Dutch, there are mentioned Farman
F.22 in their early inventory.
Can i assume those were MF.22?
Is there any good online reference on early
french
aviation products, or a good book. My referenc books are not much worth when
you need some detailed info on aircraft before ww2.
