I found this instrument recently, and I thought about taking it home. It weighs a lot, it seems all made of brass and other materials. The focuser works, the lenses are ok, but I don't know what it's for or the brand or era. I also thought of a measuring instrument, but I don't know. On the end there is that letter B, but I don't see anything else. The lens will be 2-3 cm. What do you think? Thanks

It's simpler and smaller but it reminds me of the German School Scopes by Ziess and Kosmos.

I think it's a reading telescope. IE, you use it for observing processes at a short distance. I guess it's a micrometer attached to it, which would allow measuring changes in the observed process or specimen.

Not sure what it is...but I'd pick it up anyway- it's sooo steampunk!

I've seen such an instrument, newer used in high precision tool work.  Filar type micrometer as well.  Nice piece

I was told that it could actually be a filar micrometer instrument for celestial measurements. Like late 18th or 19th century construction…

Nice piece for a man-cave.

 

One look at the mount means it's not for celestial objects. This is a telescope for lab use where (for example) a small telescope is used on a bench to observe the output from some instrument. Many possible lab applications, particularly for 1st year student courses 50 or more years ago.

 

It also appears to have a filar micrometer in the focal plane. They're seriously rare, especially brass ones that are still working.

Yes, we wouldn't use a  telescope out of the 17th century for observing either.  In other news, the sun rises in the East.
