Foxboro Flow & Valve Slide Rule


This auction is for a Foxboro Flow and Valve Rule, serial number 174305, manufactured by Cox & Stevens Aircraft Corporation (embossed on inside of case flap) This 10" simplex slide rule has specilized scales tailored to the calculation of the flow of steam, liquids, and gases. The scales don't really have designations like generic slide rules.

This bakelight rule is in excellent condition (picture shows actual item). All the letters, numbers, and gauge marks are clearly printed. The cursor plastic face is clear with a clear black cursor line. T is a 1/4 crack near the upper left corner of the cursor plastic. The case is pristine, no marks, nicks, initials, or any other kind of blemish, but some leather cracking at the flap fold lines (no tearing).

This rule is in excellent condition, with almost no scratching of the cursor plastic or the printed face to show much use. I don't think you'll be disappointed!

I try to describe items as clearly and accurately as possible. Please e-mail me with any questions prior to bidding. I'll be happy to email high resolution pictures of any detail on request.
