Hi Gordon, and welcome!
Transited thru Annecy about 2 months ago on my way to Barcelonnette. Good ATC and service, fantastic scenery

Fuselage steel jig? I built one when getting ready for the fuse of my -4 too many moons ago, and gave it away when finished... wonder what has become of it.
Good luck with your build, it?ll keep you occupied for a while, and the -4 still is the best looking RV
PS
Kinda funny how some automatically associate your country of residence with your citizenship...
