My black long bed came from an Omaha estate sale - and was bought by mistake. My coworker's wife owns an antique shop, and they got to a lot of sales. They saw a black "portable" singer with a card table and thought "Featherweight" and bought it up for resale.
They like to ask me about the sewing machines they get - and they sent me a text picture - and I informed them it was no FW - but that I was interested (thought I was not in the market for a FW).
They brought it home and I checked it out and we came to an agreement - so technically I'm the third owner, but only the second user.
They now have pictures of what a FW actually looks like. I don't think they would have bought it if they'd known what it really was, so it worked out fine for me.
