Just got back from quick lunch. Pasta with oyster mushrooms, salad.
I am not discouraged but, as you alluded, I definitely saw this when I was looking for (at Aerofiles?) the Chilean. Looked for Koppen, too. There is a very elusive Fairchild FT-1 which was a two-seat, though, form Koppen and no photo.
Maybe I take some ice cream for dessert.
