I use my 1941 Singer almost exclusively, though I have newer machines. The ONLY thing wrong with the Singer is that there is a little tiny "nub" that pokes out about 1/32" and holds on the bobbins while they wind....well, the little nub has gotten worn down so much in 70 years that it's a huge headache to make bobbins. I can make a bunch on my Sidewinder quickly!
