A couple of years ago there appeared on le Bon Coin (a French online advertising site) a Mignet formule aeroplane. I attach a copy of the image that accompanied the advertisement and apologise for the diminutive size of it (it was the best I could capture). It was being offered for sale at only a few hundred Euros. As I've said, it appears to be a Mignet formule design but not one which I recognise. Sadly before I could make enquiries of the seller, the advertisement was taken down. Can anyone out there identify it?
P.s. I should add that when it was being advertised for sale on le Bon Coin, there was a hyperlink to a video (on, I think, youtube), which showed this aeroplane being taxied frantically around a field, but my attempts subsequently to find this have been entirely unsuccessful.
