Here are some pictures of my recently restored Singer 401A. I obtained a service manual and bought some Tri-flow grease and oil from Jenny at Sew-Classics.com and went to work. It took several days and a lot of work, but it was worth it. This thing sews like nobodys business. It will sew through six layers of denim with out a fuss, when its working well.
