Shirley,
I just received a 404 yesterday and a quick inspection had a lot of fluff and thread around the bobbin case and apparently someone in the distant pass used an automotive grease gun to grease it up. Looks like graphite grease. I might need to bring it to a car wash to hose it out.
I will have a lot of degreasing before I can reapply the correct lube/grease. Otherwise it's in great shape and will be an asset to the herd.
