Hello,
I am (desperately) trying to find digitized manuscripts emitted by the chancellery of Fredrick II (roman emperor). I was able to find some relevant information here, but it only contains the text, without a proper description of the document.
I am interested in small details, like which signature was used, and if it would be possible for a child to finish it's writing.
I'm interested in those emitted from before his birth up to his 20th anniversary. The one written by the likes of Markward and so are also of interest to me (even if it's only the text in this case).
Thank you very much for any help you can provide.
I afraid OP's post will not attract due attention from specialists in the relevant field mainly on the following grounds:

What OP have found in archive.org is outdated redaction of the charter collection of Frederick II conducted in late 19th century.
Since the end of the 20th century, a new project of compiling F II's charters has been on work in MGH (Monumenta Germaniae Historica), a German leading historiographical (source-editing) institute in medieval history, linked below.

Some of the already published collection in the project series are also available at here as DD FII (1, 2): https://www.dmgh.de/de/fs1/object/display/bsb00000463_meta:titlePage.html?sortIndex=030:040:0014:010:01:00
OP may find some pictures of the original documents (charters) in these digitized collections, though not the all extant ones, I suppose. Anyway, the source/ holding of all the redacted charters should be available in addition to the text itself in the book.
