Bausch & Lomb Leica Reichert? original filter set in box (36mm diameter)
Description: Overstock from my lab. Most probably from a metallographic B&L microscope, but could be a Reichert or Leica. Not sure. Outter Ø is about 36mm and filter itself is about 19-20mm. Each has a locking screw.
Issues: none, they seem like new.
