Many years ago, I had an acquaintance with a gentleman who owned a Piper Cub, not sure if he fitted floats to it or not, but he asked me if I knew of anyone who made them. It was flown in NT, and I suspect, considerably further North.
Last heard of he was arrested in Manila. Among his posessions at the time of arrest were three passports and an AK47.
I always wonder what became of GC?
