I have 6 machines, but only named my latest.
It is a Model 66-2 Red-Head Singer Treadle. I named it after my MIL "Smitty". My FIL always called her Smitty as her maiden name was Smith.
I was very close to them and my husband told me when he was little she used to sit and sew on a treadle just like mine. She had 6 kids. I bet it got lots of use!
My MIL and FIL and treadle are long gone, but still loved and remembered and cared for! :) :) :)
I have to get busy naming the rest or else they will fill unloved and not work properly
