Hi all,
found this very rare bird Haessler H. 3, built by Ing. Helmut Haessler, good known for the muscle aircraft (-Villinger) H.V.1. Only 1 built.

Helmut Haessler's letter to Flight on man-powered flight (with photos of H.V.1 in the air):

http://www.flightglobal.com/pdfarchive/view/1962/1962%20-%200254.html

Popular Mechanics (Oct 1972, Vol. 152, No. 4) has a 3-view of the H.V.1 showing a wing closer in shape to the H-3 than to Hesham's 3-view (and historical photographs)

BTW: According to a letter to New Scientist (5 Mar 1964) by BS Shenstone (Vice-Chair of the RAeS man-powered aircraft group), Helmut Haessler "had re-designed his prewar Mufli, but he lives in Toronto and it is a single-seater." Haessler actually lived in Richmond Hill, Ontario, but Shenstone's letter makes it sound like serious work was under way on this Canadian version of the H.V.1.

From L'Air Revue 1943,

if that was not a hypothetical airplane,so maybe it was H.V.2 ?.

I may be wrong, but I think, that article just describes a then new mechanism to use leg power for turning a propellor.
It's obviously not bicycle-like and it seems to have been recommended for sail planes to give them more range and
better choices of a landing site in the case of an off-field landing.
So, no relation to a real Haessler design, I think.
