The Thulin NA was a prototype Swedish fighter plane built in the late 1910s.
The fuselage is made of a lattice construction of welded steel pipes .
The wheel ground was fixed with a spur spring under the height knob.
The Type NA was the last aircraft built by AB Thulinverke.
Although it first flew in April 1919, the poor market demand after WW1 meant that the Type NA did not enter production.
