I was recently given my grandmothers sewing machine. She didn't really use it while it was hers (my mom doesn't sew either) So she doesn't know how to thread it, or anything. It was made in the 40's to 50's, says its a Fleetwood 767-b Deluxe Automatic Zig Zag, made in Japan, but from what little i have been able to find on the internet, this was during a time that Japan was making a bunch of sewing machines to be sold in the US, and then they would just put names on them (like Fleetwood) that would seem more appealing to the U.S. As far as i can find, there aren't any manuals to be found, and one source said that these machines were based of the classic singer 15 model, but i looked at a picture and they don't really look the same. I've tried 'just figuring it out' and its not working :(
So if anyone has any info on how to thread it, or how to thread the bobbin, or any info about this machine at all, i would be forever grateful! my Google skills don't seem up to the challenge.
My next try will be taking it to a sewing machine repair shop, even if they're not familiar with this specific model, i bet they would be able to at least figure out how to use it!

I'll post a picture as soon as my camera battery is re-charged.
