Wow Jill! I know it's not a FW, but what an amazing machine.
I know that it weighs a lot, but use it at home. This would seem to be an amazing find to have with the manual and all the attachments. I'm certain it will last much longer than any other newer machine that are being sold.
Have you looked to see if there is a serial number anywhere?
If you need a machine for class or meetings, then just buy a cheap newer lighter machine.
That was really nice of your neighbor. Enjoy your new machine.
