Minty In Box Bridge City Tool PD-11 Proportional Dividers 2001 Signature Series Made In USA.

Certificate of Authenticity comes with the item.

The following is from BCT.

The stainless steel pivot mechanism is a “sliding pivot” that positively indexes to the various holes in the divider arms with stainless steel locking screws. This design feature makes it impossible for the tool to give you misleading results. The accuracy of the tool is derived from the CNC machined holes and the adjustable points (an easy factory adjustment).

The legs of the PD-11 Precision Proportional Divider are exactly eleven inches from point to point. Traditionally, proportional dividers are available in lengths from 6-10 inches. The added length of the PD-11 Precision Proportional Divider increases functionality as the index portion of the tool is substantially lengthened. Comparatively, it has an expanded proportion section, R:C (Radius:Circumference) and D:C (Diameter:Circumference) ratios, additional chord settings and one for Phi.

This tool was produced in 2001.
