Italic (and occasionally roman) mystery font in 18th-century Swedish literary anthology

In trying to help out finding Gustavian typefaces here, I ended up thrawling through old documents at, which is a good resource for swedish type from the time.

Of course, my knowledge is somewhat limited in the area. This anthology page (and the rest of the book, click through if you want, press the little "5" icon to zoom) is printed almost entirely in an unfamiliar Italic, which is clearly not Caslon but shares some similar properties. Still, that looped w, that squarish a, that oblique g, that rather extreme cursiveness... what is this? Also note the Roman capital G's supremely right-leaning barb.


(Btw, look at those crazy diacritics: ö still has the archaic form with the tiny superscript e while the ä has both the archaic and the modern form all mixed up. å seems to be most often (but not consistently) printed as â, which I confess to never having seen before, was it a failed reform attempt?)

To an extent (and Janson seems to have been common at the time), but it does differ in quite a lot of details from all the digital revivals I've seen.
