The Dornier Gs 1 (two 270 hp Maybach MB IVa 6-cyl upright in-line water-cooled engines) was under construction in Germany when WW1 ended and although it flew with Swiss registration CH-8 in 1919 it was destroyed under the terms of the Treaty of Versailles. It led to production of the Dornier Do J Wal by CMASA in Italy.
