Thank you very much, Dave and Bud!!
The destroying of the masters was not done intentionally, but was my fault when I - excitedly - removed them from my first vacuformed fuselage parts. But as much as I love Nieuports in general and Nieuport 12s in particular I can actually imagine to make another one where I'll try to avoid the mistakes I made on this one. I'm just not sure about the scale. My main problem was and still is the interior because the WDF is not really precise here (and shows mostly Nieuport 10 interior). So my intpretation was to a good part "educated (more or less educated

guess. I don't have any clue how the backseat looked like for instance
... If someone should have some information about the Nie 12 interior, he would make me really really happy.
The upper wing war totally scratchbuild, because I thought converting a Nie 17 wing would be the same amount of work like scratching it entirely.
A Nieuport 14 would be a good idea, I like the look of this machine too. But I think i'd do another Ni 12 first...
Best wishes
