Nice, that middle one looks like it was very fancy when new. I think the old Singers were very good machines, even if they don’t have all the bells & whistles of the new ones.. I have a newer, about 10 years old, Singer & it sure won’t go through heavy stuff like my old one. I have a Singer Genie, it was considered a light weight portable when I bought it, really nice for taking to classes. I’ve had it 45 years & I think it’s about worn out. My friends DH likes to tinker with them & she said I should bring it over & let him see if he can fix it up. I may do that. Someone gave him several old Singers & he’s been fixing them up, if he can’t fix mine, I may think about buying one of those for doing heavy mending & leather
