Hi Flyboyj,
>It Looks like a Kolb Mark III.
Hm ... thanks, good suggestion, I hadn't been aware of the Kolb designs before.
However, though it looks very much like a Kolb Mark III, the Kolbs all seem to have a single wing brace on the pictures I found. The Kolb also seem to have a fuselage structure of a denser net of thinner tubes - at least that's my impression.
So I think it's not a Mark III despite the great similarity. Problem is, I have no idea what it might be then ...
Regards,
