Yes! 401! I had one for a long time ...when my youngest daughter moved to lower 48 she chose it..still has it ..I just last week won one at auction..15 hours of cleaning old grease, oil feathers and dirt/ it sews beautifully on straight stitch and I am waiting for a zz stitch plate to test that feature..she sounds wonderful!
Now I am waiting for a featherweight my husband said to bid on to arrive! These machines are the easiest machines to maintain. I have worn out several machines / and so sad singers newer machines are not made like they used to be. Wore out a futura II that I loved but it didn't last. Hope you get a good one!!
