It was really crusty and seized up but I managed to free up all the bits after soaking it for a few weeks in penetrating oil. After that, it cleaned up nicely. It appears to be missing the little cup that goes between the spring and the radius rod ball.
Also...a question: The spring seems to be really small compared to the inner diameter of the main body. Is that correct?
If anyone has a spare cup laying around, I'd love to "press" it into service (pun intended).
