World's Oldest Micrometer - 1776! Who made this thing??

I've spent a couple of years obsessed with what might be the world's oldest micrometer - allegedly made by James Watt himself around 1776! However, there is a lot of mystery around this object and even the Science Museum London can't say for sure who made it. On a recent trip to London I was extremely honored to meet up with Ben Russell, the curator of Mechanical Engineering at the Science Museum, and we actually got to take it apart in their lab to see if we could get a better idea of who made this thing!

What do you think? Who made this? When does it date to? What tools did the person who made this have access to? Are those period correct for the time it was supposedly made?
