Welcome to the Quilting Board!
Here's mine with the hand crank. It still need the gold painted over and I need to rescue the black side cover from the parts and reunite it with the machine.
I would convert it to a hand crank. Gorgeous machine! I am pretty sure the hand crank from the 66 will fit. We have moved them around from a 128 to 15 and 201.Oooohh you did it. She looks gorgous. How does she sew? Enjoy!
