[suum cuique]

I have a problem with the "s" .
In the middle of a word this kind of "s" was not used.
"Kaiserreich" and "Pistole"

Enclosed is a printed example of old German lettering:

If a word at the beginning of a sentence is beginning with a capital "S", then a rounded normal "S" is used, like: Schriftbeispiel.
If a word does not begin with a capital-"S", then a long "s" is used like in "seiner".
A "s' in the middle of a word, like Beispiel is a long "S", looks like a "f"
2nd example: Was ist Aufklarung.
The "s" in Was is a normal "S" because it is at the end of the word, the "s" is not a log "S" because the "S" is in the middle of the word.
There are some exeptions when the "S" in the middle of a word is written with a normal "S" like in Ausgang.
Because it is a word connected by two words" Aus and Gang
I have my doubts that the engraving is original, because this kind of mistake is done by a lot of modern engraver.

Another example: Deutschland

In old lettering the "S" must be a long "S" looking like
DeutIchland not Deutschland.

Please see my 2nd attachement, a photo of the Luger army manual. As you can see, the word "Pistole" is written correctly with the long "s", not the regular "s".
Why should an engraving have a wrong "s" ???
