Another couple sets: http://cgi.ebay.com/INSIDE-MICROMETER-AND-END-MEASURE-SET_W0QQitemZ350017355826QQihZ022QQcategoryZ41937QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Missing a few parts, makes it less interesting to most buyers, but it has three 12" standards, so it can do 1" to 51" in steps of 1". No bids so far, with less than one day to go, and an asking price of $20. http://cgi.ebay.com/PRATT-WHITNEY-11-PIECE-INSIDE-MICROMETER-SET-0001_W0QQitemZ330206299195QQihZ014QQcategoryZ41937QQssPageNameZWDVWQQrdZ1QQcmdZViewItem This set is complete, has 3 bids ($10.50) so far, and will probably go up a bit. There are a few more as well. Even cheaper would be a set that is missing the micrometer head. However, they'll be harder to find because they're more likely to be mis-listed as something else. Perhaps search for Pratt & Whitney or Lufkin, since the rods are usually marked with the makers name. Like anything, its possible that the rods are worn and no longer accurate. You can do some testing, by comparing for instance a 12" rod to another 12" rod, or to the sum of a 6" and two 3", etc. In general though, people tended to use those things gently.
