Good Housekeeper brand?

Can anyone offer knowledge about this one? I'm waiting to hear back as to whether it runs, and what the harp area is.

It's beautiful- I'd grab it if it runs decently and has the bobbin case and at least 1 bobbin to match up. I'm sure you can find a copy of the manual online.

If it doesn't run offer them a lot less.

Looks like one of the many rebranded Japanese straight/zig zag machines. They are usually decent, sturdy machines, and $25 is a good price, assuming everything works.
