I have one of those - inherited from my mom - mine is a '47 I believe. I learned to sew on it, sewed many a pack and several tents on it before I got a machine that would zig-zag. I still have it, and was told by the dealer where I bought my Viking/Husqvarna that the Featherweight is worth up to $400. I have several attachments for mine, including a buttonholer.
