AFW - Antique France Worldwide

This antique Anci slide rule is presented here with its leather protective case, as seen in the photo. The rule features an elongated rectangular shape, typical of calculating instruments used before the era of electronic calculators. Its white surface displays a complex set of graduations, logarithmic scales, and precise markings, printed in black and red, intended for advanced mathematical operations (multiplication, division, roots, trigonometry, etc.). The "Anci" brand is discreetly indicated, in line with the keywords provided.

The transparent central cursor, equipped with fine markers, allows for precise reading of values on the various visible scales. The entire piece demonstrates precise technical craftsmanship, with clear inscriptions and a rigorous arrangement of numerical indications and graduations. The ends of the rule are slightly rounded, offering a comfortable grip and easy handling.

The case, visible in the photo, is dark in color with a smooth finish and visible stitching around the edges. It is designed to effectively protect the rule when not in use, while adding a touch of vintage elegance to the ensemble. The combination of leather (mentioned in the keywords) and the rule's materials creates a harmonious visual contrast, enhancing the object's retro character.

This slide rule is representative of mid-20th century office accessories, often used by engineers, architects, and scientists before the advent of digital tools. The design and layout of the scales are characteristic of vintage models, with an emphasis on readability and precision.

There is a patina of use on the case, consistent with a vintage object. The inscriptions on the rule remain clearly visible, with no noticeable fading on the exposed side. No chips or major defects are apparent on the visible part, thus offering a beautiful presentation for an antique instrumentation piece.
