Hai
The Nielsen & Winther factory (Kopenhagen) started at the end of WWI a cooperation with Thulin, Sweden, concerning building aeroplanes.
Thulin designed a biplanes fighter on the lines of the Nieuport Bebe, Thulin M, special for Denmark.
In some modified version this was build as the N&W type Aa.
Concerning this type there is something to find, but there were other types for wehich I need help.
I am looking for the following information/materials,
technical information, dimensions, pictures, drawings?, etc.
Its concerning the following types:
