Got a couple of things in today! First off is a Starrett 220 interchangeable anvil mic:

I've wanted one of these ever since I saw This Old Tony showing his off. The face isn't carbide, there isn't a vernier scale for tenths and there's no friction/ratcheting thimble, but it seems to be in pretty good repair. It also came with a whole bunch of fixings (Starrett 1" standard that I probably won't trust, various pins, and an extra anvil):

I also got some really nice abrasive files. The eBay listing called them "moldmaker stones," but I'll confess that I don't really understand the distinction. They're fairly coarse, but they're finer than the rough India stone abrasive files I have. They're also super thin which should let me reach hard-to-deburr spots.

EDIT: After 30 seconds of Googling, I've learned that moldmaker stones are just abrasive files that are made from black silicon carbide. Works for me.
