I'm not normally a lucky fella, but this morning I went to the markets south of Adelaide and found this old Mitutoyo 1 - 2" micrometer. Had no idea what it was worth and don't have any imperial metrology; so, I bought it anyway for $10. Researched it this afternoon and found the cheapest I could get a new one for was $86 (+postage) from the UK - happy with that.
Stripped it down, cleaned the rust of the barrel, plunger and lock lever with scotch bright and it came up nicely. Oiled everything, put it back together, zeroed it and checked it for accuracy - spot on. Unfortunately, the coating on the lock lever is a little thin in places and the plunger is a little pitted, other than that it's good nick.
