Royal Danish Navy - purchased one W.29 from Germany in 1919, building a further 15 powered by the 150 hp Benz or 160 hp (120 kW) Orlogsværftet O-V six-cylinder inline engine under license at the Orlogsværftet (Danish Royal Naval Dockyard) as the HM.1 from 1921 to 1927, the type remaining in service until 1930, being replaced by the Heinkel HE 8.
Hungarian Soviet Republic ordered production of the W.29 at Ufag to restart. At least two were completed, which together with the single W.29 completed for Austria-Hungary, were operated by the 9th Floatplane Squadron operating from Cspel near Budapest.
