Some micrometer history

I saw it all on the internet so it must be true . Is this one of the first production mic's from Brown & Sharpe ? After they bought the patent form Palmer . It's for sale on a popular auction site .
Here is some fun history .

Also a good read .

One detail I have never found is if in fact B & S bought the Palmer patent, or just licensed it. The patent dates from 1848 so it may well have been expired by the time B & S saw in Paris at 1867 exposition. They could have just used it but always did give Palmer just a little credit.
