About This Piece

A slide calculator worked with a stylus, with an addition panel on one face and a subtraction panel on the other, and a carry mechanism clever enough to borrow and carry in a single movement. The columns are laid out for pounds, shillings and pence with a farthings column, which means this one could only ever have been used before Britain decimalised in February 1971.

Important Info About Antique & Vintage

Every antique and vintage item we carry has lived a life before arriving in your home. These are not factory-made products. They are objects with history, character, and the marks of time.

Age-appropriate wear, patina, minor imperfections, and signs of previous use or repair are inherent to antique and vintage items and are not considered defects. These characteristics are part of what makes each piece unique and are often what give it its beauty and value.

We describe the condition of each piece as accurately as possible in the listing. If you have specific questions about a piece before purchasing, please reach out. We are always happy to provide additional photos or details.

Colors may appear slightly different on screen due to monitor settings and photography lighting. We do our best to represent each item accurately.

Descriptions, dates, attributions, materials, and measurements are provided in good faith and reflect our best assessment based on research, physical examination, and the information available to us. Antique and vintage pieces often carry incomplete or unverifiable histories. Where a detail is an assessment rather than a confirmed fact, it is identified as such. Measurements are approximate. All items are sold as-is, with the photographs and condition report governing.
