Jason Clarke Antiques has dated this piece to the Victorian era.

This example has a brass column support with superbly cast finial with honeysuckle motifs. The brass beam culminated with a ceramic scale plate bearing the manufacturers name to one side and a cast iron balancing bowl with brass weights. (please note, brass weights are not original to the scales)

W&T Avery were the foremost company making weighing machines during the nineteenth century. With a rich history reaching back into the early eighteenth it was not until the 1818 when William & Thomas Avery renamed the company and made it into the name recognised today. Their success was so great that the company owned three manufacturing plants within the Birmingham area. It was finally consumed by GEC in the late seventies.
Circa 1880
