I have the following focus block that I would like to sell. It has 5 cm travel and the fine focus has 100 microns per revolution, the fine focus has limited movement of 14 revolutions after that you have to move it to the other direction. It has hole of 42mm to mount an Olympus BH2 head and has the slot to mount a Olympus BH2 nosepiece.
If anybody is interested then send me a PM with your offer.
