About This File
the original Nieuport 17 skin was made by Rabu. it's the Escadrille 65 stock skin.
the heart was borrowed from OBD skin for Werner Voss (D.III), which I believe was done by Paarma. I had to distort it quite a bit to get the face to fit over it.
the face was rendered free hand on a piece of paper and then scanned.
I made up a new bogus serial number to replace the original.
finally, I picked the name "Mathilde" because it's based on an old Germanic name that means "mighty in battle", or some such thing.
