Does anyone have photos and drawings of the FF.17 in both 17a (single float with outriggers) and 17b (two floats) incarnations? All I can find online are the below.

Hard to find Zac.

In my list,

DD II was a single seat fighter quadruplane
D II was a single seat fighter biplane,also assigned to FF.54
D.V was a single seat fighter biplane,no more details
C I was a reconnaissance biplane
Quadruplane was a reconnaissance aircraft,no more details

It helps to know that the prototype Friedrichshafen C I was a land plane conversion of a model CHFT (FF 33L), Marine nummer 1267. So, the C I prototype retained the FF 33L's span of 13.30 m and 160 ps Benz Bz III engine. Either a second, Mercedes-powered C I prototype was built or the ex-Marine nummer 1267 was re-engined and slightly modified.

@richard B has noted that "There was only one Friedrichshafen Vierdecker , the FF 54 , designed by Diplom-ingenieur van Grieß ..." Does that mean that this your DD II was the same as the FF 54 prototype? Or was the DD II simply an unbuilt project?

Concerning the FF54 (and contrary to Lange) Jack Herris in his Friedrichshafen Aircraft of WWI (2016) writes “…There is some information that indicates the FF54 was also known as the D III, but that is not confirmed, nor is there any information on an intermediate Friedrichshafen D II design…” (p. 266).

By the way the designer of the FF54 was van Gries and not van Grieß (Lange, Herris).

DD II unknown.

D V single seat fighter biplane with in-line engine and lower wing under the fuselage according to Lange. No more information.

I agree with Apophenia concerning the C I.
