Are these scales still accurate?

Most antique brass balances are sold as decorative or historical objects rather than certified instruments for modern measurement. Over decades, tiny changes in the pivot points and knife edges affect their precise calibration. While many still move freely and balance correctly, they require professional adjustment if intended for actual weighing tasks. Enjoy them primarily for their mechanical ingenuity and visual presence.

What is a postal scale?

A postal scale is a small domestic balance designed to weigh letters and parcels accurately to calculate correct postage rates. They became widespread during the Victorian era following postal reforms that standardised letter delivery fees. These pieces typically feature a brass platform or small hanging pan paired with a graduated fan dial or upright indicator. Their compact size makes them popular for desktop display.

Why do some scales have stamps?

Official verification stamps indicate that a local inspector tested the instrument against legal standards for commercial trade. These government marks ensure the scale performed honestly in grocers, chemists, and post offices. Collectors value these stamps because they provide verifiable proof of period use and local history. They often name specific cities, boroughs, or regulatory companies.
