This is description of this part:
A cap (cover) engraved with the manufacturer's logo and the model name "M-9." This coap covers and holds the spring, which is part of the mechanism that focuses the vertical slide. The plate also includes the serial number and year of manufacture (1938).
The M-9 microscope was manufactured before World War II at the Soviet Progress (later Lomo) factory. It is often believed to be a direct descendant of the small MBI and MBR series microscopes, but this is not true, as the MBR-3 and MBI-1 are copies of the German L-Stativ.
What is this part needed for?
- On the secondary market, you can find M-9 microscopes that have been repaired in the past and are missing this part.
- Also for those who simply lost this part during microscope service.
- For those who have this plate, but it's damaged.
