Would be good to put any & all info on these complicated jewels of boring heads together. I'll start with a foldout that came with the usual operator's instructions.
Mine is a UPA5 - S6. An older version, I suppose, as none of the current info I've found refers to my version. I'll be taking it apart for cleaning & inspection. Of course I'll document my progress & post on this site. I haven't scanned the Operator's Instructions mentioned above. But a newer version is attached.
