yes, I have very fond memories of thet tredle machine,I was about nine yrs old,the one thing I still remember is the bobbin, I always thought it looked like a bullet,it was about an inch and ahalf long and to a sharp point on one end.
one day my mother gat upset and tossed it out literly,I remember crying, but what a long ways they have come now.
I have my mother-in-laws tredle machine now and cherish it.
