Can anyone point me into a direction on where to get an explosion drawing or other repair related documents of the Zeiss Primo Star (first gen) - my focus knob is drifting out of focus and I found that a little teflon seal between the coarse and fine drive is broken which most likely caused this problem (the grease of the coarse drive to be more specific) - having removed the left fine tuning knob everything works fine but if it is connected the problem occurs.. I think I need that new seal and maybe some cleaning of the grease..

What do you think, does it look like yeast contamination? 2nd pic is at 65x
