End the end of WWI the Dutch naval forces received some Thulin K and LA from Sweden.
Now I am looking for all kind of technical etc. information about these aeroplanes and during that I found /received also information about other Thulin types.
There was also a Thulin M, based on the lines of the Nieuport Bebe. This wAs build with some modifications in Denmark as the Nielsen & Winther typ Aa. I found also that this came because there was a cooperetion between Thulin and N & W.
Concerning this type there are pictures/Drawings etc to find on the internet.
But there has been also some other types, Ab and Ac.
Then further in the range B until with F, this was. The Fd.
Who can help with more information/materials concerning these types
