Thank you everyone for your input and knowledge! I think this was the first White Rotary brought to him, but he figured it out and cleaned out the bobbin case and parts and now it is sewing! Caroline, I think my machine might be just like yours except maybe the cabinet, and actually a Family Rotary. It didn't have the manual, but I found some online that appear to be identical to my machine. Franklin Rotary I guess was the branded name put on the machines sold by Sears. In their manual, the machine head looks just like mine. I am excited and relieved, i think it will be a very good machine. Thanks again!
