C3 Mini Lathe Milling Attachment Questions

This post seemed to have disappeared somehow, so here it is again:
My C3 Lathe arrives today! Meanwhile I've been getting the milling
attachment in a fit state to use. Has anyone got experience of stripping down a C3 Milling Attachment? Here's a photo: http://www.mini-lathe.com/Mini_lathe/Accessories/accessories.htm#mill
Beneath the graduated aluminium ring near the top of the photo is a dark steel block containing a bearing. I've rinsed bits of swarf out of it with paraffin, but it doesn't appear to easily dismantle, making thorough cleaning and regreasing difficult. Any advice on this problem? Also, the graduated aluminium ring rotates with the handle but can also be turned by hand independently. This 'slip fit' is controlled by curved spring wire. Should there be just one piece, or have I lost the other? Cheers, Scrim

No need Scrim. It came in yesterday, the day you sent it.
