Could you tell me, please, did you derive your identification of the image as a sighting tube from the words on the manuscript page or from another source?
I also think a sighting tube would have some sort of protractor or armillary sphere attached or shown nearby. But sighting tube does make for a much more easily understood and logical ID for the image at such an early date.
Alas, I can barely read and understand English, much less any other language.
Thank you.
