Hermes 5700


Well, I know this is very off-topic, but I don't know who to ask.

I've recently got a used Hermes 5700 desktop calculator (an adding machine), very tough, and still working though it must be 15 years old circa.

Of course, people who gave it to me (for free), were happy to get rid of that old "rubbish", and they didn't care about the original case (if any) or the manual, which probably got lost many years ago.

Apart from the case, is there anyone of you who knows where to find documentation about its usage? A manual? A bunch of instructions?

Thanks in advance, even if you cannot help me.
