Ken,
The Kenmore 117-552 was made for Sears by White in 1954. I have two others like that but different numbers and they are excellent sewing machines. Well worth refurbishing.
I also have on of the White embossed machines. But mine is electric. Looks the same as yours but has a solid hand wheel rather than a spoked one.
Congrats on the acquisitions, and have fun with them.
Joe
