I'm guessing it's a refurb too but the details have a sort of home made look about them, not like it came out of a shop specializing in refurbing old machines. The "Singer" on the front is definitely not original. The triangle decal almost looks hand painted too. If you want to custom paint one this is a good choice. You can't hurt it.
66s are nice machines. I never tried FMQ with mine but it did everything else very well.
