JCon; The type 86 or KdF car was never produced, the website you posted uses the name KdF car, but does not clarify that the KdF car which was not built is the type 86 civilian vehicle, not the type 87 military vehicle, of which 564 were built and look very similar. Variants of the type 87 include the type 187 and type 287. Schiffer's
VW at War, volume II, page 26 and 46 give a breif overview of this vehicle and it's use.
Rob; the first site you posted calls this a type 98, Schiffer lists a type 98 under Schwimmwagen A, type 128 variants. I can't find any other reference to a type 98 as being produced. How this is different from a type 87...?
I notice there is a box art which implies the Luftwaffe used type 87's;
