Peridier Filar Micrometer by Manent

 

A large filar micrometer made by Manent. It has a long sleeve that fits in the focuser base once you remove the drawtube with the focuser on it. This has two readouts for measuring.

Cover and eyepiece holder removed, showing the two slides. You can see the two pieces that hold the threads, along with the pins to hold the missing two pieces.
