Physically, the objectives are well preserved, showing normal signs of use consistent with professional laboratory equipment.

Standard RMS thread, compatible with a wide range of microscopes.

A great opportunity for:

- Collectors of scientific instruments
- Microscope enthusiasts
- Laboratories looking for classic high-quality optics
- Decorative or educational purposes
