cleaning voitglander rangefinder?

[Rob]

I got a add on rangefinder that I need to open to clean it up and adjust it vertically. I took all the screws out but it did not come apart. Anyone know the
secret to opening one of these?

 

[Rob]

Got it! Someone on Classic camera repair had the answer. Loosen the screws in the front of it and push on them. Mine was tight to open. I cleaned it all up and it works fine now.
The vertical adjustment is located under a plug in the bottom of the rangefinder. It controls a tiny cam to make the adjustments. Final adjustment is done once it is reassembled. It is nice and bright now, before you could not even see thru it. If this can be moved to the repair section that would be great.
