WONDERFUL DELICATE BOXWOOD & BRASS ZIG ZAG RULE

Lovely and finely made rule measuring 37 1/4" in total length. 12 sections and each is a shade under 1/16" thick (thin!). The sections are held together with sturdy brass rivets and there are solid brass caps on the two ends. The rule has been graduated but there are no number designations and no makers name. Early and excellent.
