O.Thetford, P.Gray German Aircraft of the First World War (Putnam)
Only a single example of the L.F.G. W two-seat reconnaissance seaplane was built, No. 509. It was little more than a modified Albatros C Ia airframe (which machine L.F.G. built under licence) mounted on a float chassis. The floats themselves were unusual in being of basically cylindrical shape with two deep built-on steps. Seaplanes were built at the L.F.G. Bitterfeld plant and did not bear Roland trade mark. Engine, 150 h.p. Benz Bz III.

LFG Roland W1
The L.F.G. W1 was basically an Albatros C.Ia, which L.F.G. built under license, fitted with floats. L.F.G. built seaplanes at its Bitterfeld plant and these did not carry the Roland trademark, but all L.F.G. aircraft are frequently called 'Rolands'. The engine was a 150 hp Benz Bz.III. Only a single aircraft, assigned Marine Number 509, was built.
