This machine was built at the Sint-Job-in-'t-Goor airfield, Belgium, in the hangars of baron Pierre de Caters, by the Swedish inventor Janne Mellander, who lived in Antwerp at the time. In 1911 he was granted French patent No. 422954, which disclosed some details of his rather fragile-looking machine, which was equipped with an automatic stabilization device and had the wings mounted very high on a secondary fuselage.
