I have a 1941 Featherweight that I found when I cleaned out my in-laws home a couple of years ago - you will love using yours for quilt tops. I found the best book for learning all about your Featherweight and how to maintain it - it's called The Featherweight 221 and I by David McCallum. You can email him at :
