    Default Cool depth micrometer


    Bought this on eBay recently—was curious why the box it sat in was so big—there wasn’t any pictures of it out of the box that showed it’s special shape

    I’m embarrassed to say I won the auction with a bid of $13.99

    Neat old mics are pretty cheap right now. I have been collecting for 40 years and some really good stuff sells for nothing. But other can bring good money, just depends on who is shopping that day.

    It is a very cool mic. Thanks for posting it.

    That's really neat! It doesn't appear in any of my Lufkin catalogs.

    That is very cool. I very caually collect oddball mic, none especailly old and it all started with a Shardlow "anglo-metric", next was a NIB Slocumb digital. They make great desk-top distractions!

    Ya, I collect odd and just plain neat old micrometers too. By chance is your anglo-metric Shardlow the "Madison Patent"?

    The graduations numbered both directions off a centre witness on the barrel suggests it was for checking down-hole or down-slot groove width as well as position in one go?

    Same again the half-round shoe.

    Betcha the thickness of the skirts on the rods are a standard thickness to make the math easier?

    If not a 100% "custom", then there was at one time a niche in a major industry as needed that capability set to avoid clumsier kludges.
