This is a pair of Mogey 3 inch telescopes. They probably date from the 1920’s or so. The one on the left is completely original except for the tripod, which I made. The one on the right was a mess when I got it, with a very strange declination housing. Here’s a picture.
The Declination housing was made from a Right Ascension housing from a very old Alvan Clark! Have a look at these pictures:
So that may be a project in the future.
There are many details about the restoration of the Mogey mount here:
You can see a video about these two scopes here Mogey Telescopes.
