Elliott micrometer

I have just acquired a micrometer marked Elliott London, it is quite old and has 1/2" range, but is dual reading. The thimble has a sliding sleeve which brings into play 2 sets of divisions, and there are 2 cursor lines each set at an angle to the screw axis, one line is marked "English", the other "French", I would be interested if anyone can help with information on the mike, I can find pictures of an old single reading mike, but not dual reading.

Nice piece as a novelty item. Never seen one like it.

You might just have something of value to a collector there.

I once bought an unusual micrometer at an antiques fair for £20, and sold it on ebay to a collector in America for £2600 !!

I wish I could find another one like it, but apparently mine was one of only two known to exist.

Lovely lttle micrometer, Chris

I've not seen anything about the dual-reading version, but this seems to date the 'family' to the 1870s **LINK**

Thanks for your help folks, I was wondering if I had found Elliotts Lesser micrometer!!

Michael, thanks for the link, I had seen that, I cannot be sure if mine was made by Elliott before the brothers came on board. There is a big space between the Elliot and London on one side of the frame, maybe room enough for Bros, but it is worn there. The whole thing is made of nickel silver apart from the screws. There is also a ratchet on the end of the thimble.

On the other side it looks like the owners name has been hand engraved, but the text is worn on the middle, it could read T? O'Gorman or Goeman. could this be a famous engineer?

I also found out the Museum of the History of Science at the Ashmolean, Oxford has the Elliott archives and many instruments they made back in the day, but my initial search could not find a micrometer like this one.

The only thing that I can add at the moment, Chris, is that one of the single scale versions was listed at auction as a 'Gunmakers Micrometer' ... but of course this may be a complete red herring.

Michael, I saw that too on an auction site, but could not find the price it went for, but there are similarities, bearing in mind these were probably hand built.
