North, mid 18th century, Berlin.
German drawing set mid 18th century, in a wooden case covered in finely tooled leather. The brass protractor is signed North fecit Berolini. Virtually all of the brass instruments are missing from this set. The brass dividers in the top slot are probably French and not original to this set. The wooden diagonal scale is graduated into 2,62mm Rhineland inches (rheinlandische Zoll) at 1/10th scale. The brass protractor measures 133mm at the base and 84mm from the base to the apex. North is presumably an English maker residing in Berlin, but is not recorded in any of the standard references.
