This suggestion actually makes sense. As supported by stylized Mortar and pestle JanS posted below.

The dot above all known Sparkasse logos that have it (like depicted here: https://www.sparkassengeschichtsblog.de/...cklung.jpg) is representing a coin beeing dropped into a piggy bank and is always centered above the letter "S" and the letter itself has the "whitespace" always aligned in a horizontal fashion.

John's suggestion of a stylised Mortar and pestle seems to match with the off centered positioning of the dot representing the pestle stem (something like this: http://clipart-library.com/clipart/289402.htm).
The fact that no google image search on either the image itself nor a picture search with a "mortar and pestle logo" search phrase turns up anything useful leads me to believe that the organisation that used that logo is no longer in existence. It might be helpful to know the year of manufacture of the calculator to narrow down on possible candidates that were in existence at the time of manufacture - possibly starting with the letter "S" in their name.

Maybe shoman24v can provide the S/N or identify the date of manufactre himself (https://www.hpmuseum.org/collect.htm#numbers)

Nice Calculator !

I think you and john gustaf stebbins are on to what the logo could be. I tired to look up the lineage of the Sparkasse logo and couldn't find anything, but you did. Definitely not that.

The S/N of this unit is 3043A01636, seems to be fairly early.

I was going to use this SX as a replacement for my another I keep in my desk to use from time to time. Having to press the bezel on that one was getting worse, but the more I think of it, maybe I should keep this one aside. Interesting logo, fairly early.
