S1C, don't even think about it. Buy an S1S or T. any other S1 has non symetrical wings or is probably a heinz 57 job. Beware of highly modified stuff. Curtis new what he was doing and anything other than a Curtis by the book Pitts is probably a heap of smell stuff waiting to be off loaded at a probably cheap looking price. Beware the to good to be true Pitts S1C/D bargin!
