The following vehicles are amongst the rarest of the rare. The first series of Schwimmwagen produced was called the type 128. The wheelbase was longer than the more common type 166; the type 128 had a lenght of 4,2 meter. After a full design review the smaller type 166 was developed. The first 125 of this series are believed to be hand-built by Porsche in Stuttgart.
