This is description of this part:
This is the part responsible for the audible and palpable "click" when rotating the revolver, and for the revolver and the objective lens stopping in the correct position. This part is a plate that fits into the appropriate recess (detent).
This particular unit was used in a Will Wetzlar V265 microscope.
Objective nosepieces in Will Wetzlar microscopes of the V100, V200 and V300 series have the same construction, and to the best of my knowledge also their equivalents sold by the company Hund Wetzlar - therefore this element should fit all of them.
What is this part needed for?
- service part - this element is damaged quite often
