33General: I am starting to feel a little reluctant to part with it! Particularly as I looked inside and found that it's quite sturdy and well-built. Maybe it's more a "late 60s" rather than a 1970s model - they hadn't switched over to plastic parts yet.
pennycandy: Yes, it's the same. Unfortunately I charged in there with Q-tips and scooped out a lot of the grease! I have a new tube of sewing machine grease, though, so I'll replace it with fresh so it looks the way it did before I blundered into the box.
