I've seen that Kansas City name here before in relation to refurbs like yours. When the work was done it was just another old sewing machine. They didn't have any collector or antique value then. Old treadle machines were modernized by the thousands with the addition of electric motors and the crinkle paint jobs that were popular at the time.
Now we look back and want them original but in the 40s people just wanted a sewing machine that worked.
