A good pair of dividers made in brass and steel bearing the intriguing instrumentmaker’s mark, a Pelican. We know that this mark was used by a German maker but we don’t know who. I owned a folding rule with the date 1721, so we can date this pair of dividers circa 1710-1730. The instrument is in fine condition, the point not reduced. 11cm lenght. Read More...
