After comments made I investigated further on the net and there is some question as to the correct name of this aircraft. It looks very like a Donnet-Leveque and the links I've followed seem to raise doubt as to whether it is or it isn't. Therefore as I cannot be 100% confident that the name I have is correct I decided it would be best to declare this one nul and void.
I should add that another source refers to the same picture as the OV Flyvebad Maagen II which raises further doubt, since the Maagen II was the name used for French built Donnet Leveque's! One for further research I think!
