Correction: My Wetzlar has three objectives, not four. The microscope is my prize possession and it is OK that it does not work perfectly. I do not intend to risk having it refurbished. It is an example to me that 130 years ago such precision was even possible. Quite remarkable. That being said, one of the objectives, not the lowest power, or the oil, still has remarkable image quality.

I think references to a single objective microscope were to the original poster's picture of the rotating stage microscope that he bought, not your Seibert. Seibert did make excellent optics , as evidenced by your image. It amply answers the question of whether antique microscopes have useability or not.

The scope safely arrived today, the condenser is actually complete... Fine focusing wasn't working, so I disassembled everything immediately :mrgreen: didn't take a picture before...
All the parts inside look healthy, so probably something was a bit out of place... Microscope is built superbly, the precision is fascinating... The only real problem are the fungus in the mirror, so a small parts are not reflective. But probably will be usable anyway...

Whoever was using this microscope was a heavy smoker, maybe a pipe smoker, or probably the whole lab was... I feel like I'm cleaning an old pipe. A Balkan lab from 1920s-60s or whenever was this used :roll: ... I actually used to be a pipe smoker and remember the smell when cleaning old pipes... I should soak the whole thing in 100% alcohol

A never ending wipe...

I'm pretty sure I have seen that model of scope before. An old Reichert.?

In case you are puzzled by the stage clip arrangement for the second Reichert.
Here a few pics from a similar system of an English stage. A CTS:

The grippers slide into the wedge shaped channel at the back of the stage and can be widened or narrowed depending on the width of the glass slide

The wedge is attached to the gripper by a couple of screws, one of which has a knurled head for hand tightening.

Beck also used the same sort of system at one point ...with a less fancy slide gripper:

...I did squeeze a lump of warmed polycaprolactone (model making granules .. "Polymorph" ) onto the groove and it flowed into the groove and took the shape well :-)
So doing something along this line might work, for something?

Does that use a 52mm glass stage?

woyjwjl.... that is a wonderful looking stage.
It would be a brilliant way to look at an insect mounted on a pin, from all directions.
I am very envious :-)
