Well, it sounds like you've come to the right place. Cleaning up machines is what we do..... many are better at it than I. But, from what you say, I don't think the job will be real tough. You might want to watch muv's video about cleaning vintage machines in the vintage section of QB. Get all that gunk off the machine and then oil and grease it. I oil and grease mine every couple of weeks if I'm using it a lot. It will just hum so sweetly when it's gotten its oil bath. You can download a manual for the FW online for free. Good luck and keep us posted.
