Long answer short, this is:
This creation found its way into the shop. Still not sure what to make of it!
German makers marque. The internet provided some clues, as usual.
Mustang model, 15' long.
Sealed flotation in the ends, with a hatch for storage.
Love it or hate it, it needs some 'glass patching, smoothing and paint.
Third seat to be put back in, might not make a bad kid hauler and/or fishing machine.
Similar model from the web, with tractor seats. Now we know what the cords 'glassed into the sides were for - flotation.
Stay tuned on this one....
