Thank you for the help I have been given. We found out my girl's serial number is G0062681 and turns out to be a 66 born May 28 1923
To find a manual, I went to
http://www.singerco.com/accessories/...manuals/search
and put in 66. I see a manual for a 66 treadle, not electric.
Can someone help me again? Thanks!
