It is a Singer 301 which is a terrific lightweight sewing machine not much heavier than a featherweight. I already had a beige and white one that is my favorite portable machine and I had been on the lookout for an affordable black one for ages! It is gear driven so it runs extremely well. I found this in an antique mall in Cheyenne Wyoming. At the time it wasn't running well so I reconditioned the motor and she runs like a beauty now!
My everyday Juki sewing machine needs her annual servicing so I think I'll use this machine whilst Juki is in the shop!
