I found this worn old sewing machine last week—now to see if I can restore it and get it to work! Currently, at minimum the treadle doesn’t move, a belt needs replacing, and it needs a TON of cleaning. Thankfully it came with the original manual, so I have a diagram with all the mechanical insides labeled to work from. I did some research that suggests it’s from the late 1920s, so very likely still being used in wartime. Best part is, it was free! (And funnily enough made by the Free Sewing Machine Company).
