I've never seen one, either, though I know that there are some Featherweights out there with the centennial badge. But at around $3K, they are way out of my league!!! I hope this 66 finds a good home. On another note, I got a green 185 via USPS today which I won on E-Bay. Unfortunately, the machine was dumped in a box with a few pieces of styrofoam tossed in. The case was shattered, the motor mount was completely broken, and the machine is so badly damaged that I doubt it will never sew again. I've asked for a refund. Keep your fingers crossed.
