Wow.. interesting info on the Featherweight. Jane, right now, I'm not considering getting rid of it, because it reminds me of my great-aunt who taught me how to sew, and I used that machine to do all the sewing I mentioned in the "True Self" thread. Now you guys have me wondering if I should recondition the Featherweight and buy the parts I need to get it back in business.
I found the instruction manual for the buttonhole attachment (which is a little more complicated than the ones they have today, to say the least), and the copyright on that was 1939, so I believe this one is the one I have based on the date and the picture:
