Oh man am I ashamed, and me that can spot the difference between a 93 and 96 Ford Mondeo at 50 meters distance while driving. I looked at the number and shape of the sidewinods, the tail and the basic position of the engine intake. I guess I should've looked thrue all Pipers at Airliners.net first. My apologies to Stefan, I thought the oversized bulge of the nose was due to the drawing style since I did think it looked bigger than the Seneca but after googling Aztec I can see now it was very accurate.
