Interesting examples indeed! In 2021 I gave a workshop about 18th century Kurrent in the Staatsbibliothek in Berlin. I had had interest in Kurrent before, but in preparation for this workshop I did a lot more research. Kurrent was used roughly from the 15th to the early 20th century and got through
many stylistic changes, as it was a practical handwriting style (so to say the everyday sister style to the more formal chancery scripts and to Fraktur as the most formal style that was also widely used as fonts).
So you can’t say there is
the slant for Kurrent. It basically existed with a left leaning slant, upright, and right leaning slant. It was written over the centuries with a quill (broad pen), with pointed quills and steel pens (that started influenced by English Round Hand in the late 18th and early 19th century) and in one of its latest iterations with a monoline nib (Sütterlin German Script, Sütterlin also existed as a "Latin" aka English script style). That was again written upright and
meant to be changed by the maturing writer. It was a "Schulausgangsschrift" (basic school script, mostly meant to be as a simple pure style, easily to be learned and open to changes regarding use of nib, slant, letter forms, as long as they stayed recognisable). A very different approach than Palmer’s for example
.
Latin aka English aka Copperplate was used paraellel to the "German" aka Kurrent styles – sometimes in the same body of text. Proper names, places, words from other languages like French or English were the most common application for Copperplate. It looks pretty weird as the x-height of Copperplate in the same text is usually much higher than the x-hight of Kurrent.
Btw the "w" in the first example is the most common form of "w" in the English master scribe books of the 18th century, look in your Universal Penman
