Didn't take a pic before ripping into it, so here it is just after. I cleaned the dirt off with WD40.
And the finished product. I love this machine: Any reservations I had about not having enough space are gone. This was very necessary. Wood cleaned with (1950s bottle of) marveer wood cleaner.
It also came with the twin needle, which works beautifully.
EDIT: Oh, tri-flow throughout, and she sews like a new one.
