Thanks LM - in fact I eventually found it through Mechta's link. But it has got me looking into the history of the Tailwind. Seems N374 was the prototype W9L and the 3rd Tailwind ever built. Its much "slimmer" than todays newer Tailwinds which coupled with the unusual undercarriage and tail was intrigueing me! Anyway its still around today, albeit its now been converted to a tail dragger.
