Gunther sent me photos of this replica Hafeli DH-1 at the Fliegermuseum in Duebendort, Switzerland. Six of these aircraft were flown between 1916 - 1919 and were a two seater reconnaissance aircraft, they were not very successful.
Des.

A pity they weren't more successful, certainly an attractive machine. Thanks for sharing the photos.

Story:
August Häfeli worked for the firm "Aero-Werke Gustav Otto" (they also built the first Otto-machine for the Royal
Bavarian Airforce in 1912) before he went to K&W.
At "Gustav Otto" he was in charge of the AGO C 1 aeroplane.
The Häfeli DH1 largely corresponds to the AGO machine.
The DH-1 (M1) was not successful, 3 crashed in 1917; the hook was a try to enhance braking while landing- but was too dangerous; in 1919 the remaineing 3 machines were scrapped.
Why ( and what ) flying characteristics weren't satisfying I couldn't find out.
viele Grüße, Gunther
replica built at BAMF / Buochs, Suisse and Interlaken (between the lakes), Suisse; 29.02.1982-24.08.1985; 9710 workhours;

Messieurs!
Looking at the tailplane and how both are hold together one may assume that it was a "swinging" fuselage; the bond couldn't
have been as stable as on a P-38 Lightning or a DH 2 (lot of rigging to stabilize).*
It also may have been tail-heavy and take-off/landing might not be easy... .
viele Grüße, Gunther
*... the tail booms look sturdy but not the way they are fixed to the wing struts and bond together at the tail end

It's an interesting looking machine, that's for sure.
The banded woodwork on the tail booms is very intriguing.
