Hello HP41 fellows,

now it's the final stretch.

Final Assembly

Oh well, the screw dealer did not get into business with me because I thought of my other hobby: Listening to LP Records with magnetic cartridge pick-ups. I've found a matching mini-screw in my small fundus of cartridge fastening supplies which just does the trick to close the HP41CV case thoroughly even using the shortened/damaged post:

So with this I went to putting it back together:

To get the rubber feet fastened I'm using fresh thin double sided glueing tape and with this I seem to be done. The thing works again, so let's see how this repair last for the longer term.

In retrospect, just a little clarifying side-note:

The cleanser I used was explicitly stated "acetone-free".

So, thanks for all the useful hints and information!
I hope this repair documentation will come in handy for some other HP-41CV users suffering sudden "outage" of this brilliant calculator!

Best Regards,
