DescriptionFolding bevel with brass blade and boxwood beam protected by sheet brass at its ends. Though 1/16" short on each inch, both components are numbered and graduated down to the 1/4" on one side and 1/8" on the other.Label TextFor copying angles other than the 90 degrees regulated by the common square, an adjustable bevel was needed. Dated 1779, this example doubles as folding one foot rule, but for a non-British standard; each of the 12 inches it marks only measure 15/16”.Mark(s)Stamped into the end opposite the hinge are the date *1779* and *WH*, likely an owner's initials.
