As a response to the rising threat of Entente flying boats, the German navy developed several
Jagdeinsitzer Wasser (Seaplane fighting scouts) in 1916, including the
Albatros W.4. Though it was derived from the Albatros D.I, many details were changed (beyond the obvious addition of floats), such as a wider wingspan and wider gap. Various types of floats were tried as production ran along, and 118 were built before they were supplanted by Brandenburg types.
This is the late-production version of this plane, with a wing radiator and late-model floats. An early-production model is also available. At 1:144 scale, you get one paintable aeroplane per order. At 1:288 scale, you get two aeroplanes -- one early and one late-model -- connected by disposable links. In clear plastic, the 1:288 model has propeller disks which you can detach and mount after painting.
