You either love antiques or you don't. I could ask what the fascination is with Bow Tuck bags, or One Block Wonders. We don't all like the same thing...
I love my 108 year old Singer treadle because it still works as well as the day it was born. I marvel at the balance and precision it has. The soothing sound, "tickety-tickety-tickety", now you don't hear that from a modern machine. The bobbin winder mechanism is a marvel for it's day and time. I feel connected to a people and time when there was pride in making the very best product you could make, not planned obsolescence. It is a fine example of MADE IN AMERICA. My machine will still be sewing when your computerized, multi-thousand dollar plastic housed one has to go sit in the shop!
