    you keep mentioning 'unscrewing.' Are the parts you are separating unscrewing, repeated spinning in one direction? Or are they bayonet mounts, where you twist it about 50-809 degrees and pull apart? I think this is important to clarify. Unscrewing the black-edged unit can lead to the prism possibly losing its proper orientation.

    There is actually a tiny notch in lens element that lines up with recepticle in housing . It all lines up. I'm excited to try out on my T when I get it back from Harry.

    Is there? That's good to know. My Rolleinar viewing lens is a bit dirty but I've been hesitant to open it up. I wasn't certain I could get it oriented correctly again.

    To be clear, Todd and Brian, if I unscrew the viewing lens setup, I will find a notch in the prism lens and a tab on the body, and reassembly will be easy? Thanks.

    Absolutly.. I found this out by accident.. The lens had fingure prints and dust. Clean it up perfect. Notches lock in perfectly. Got to love German engineering. They thought of everything.

    Remember... these things were assembled by mere mortals, not optical engineers/scientists, so they have to think about details like that. Most who work assembly line jobs are not necessarily highly skilled labor.

    Thanks for the info. The first TLR close-up set I had was Japanese- Acura brand. It needed some serious cleaning on the viewing lens and I opened it up. It wasn't hard to re-orient the prism- just rotate until the image was at its top point- but certainly no indexing or such.
