This Fokker Dr.1 Dreidecker (Triplane) replica was at the Omaka Aviation Heritage Centre near Blenheim. This is an excellent aviation museum with many of the exhibits airworthy and flown at airshows, as are more of the Jasta seen (in the PiP note) parked indoors.

I couldn't resist this musical clip which has video of an original Dr.1 with its most famous exponent.
