Postal scale

In 1840, a postal scale was registered by R.W. Winfield, of Birmingham. This “candlestick” pattern of spring scalewas introduced at the same time as the penny post. R.W. Winfield & Co. was a large manufacturer of brass bedsteads, cots, sofas, chairs gas fittings, chandeliers and general brassfounder's items. The vertical scale on the left was calibrated up to 4 “oz,”with half-ounce divisions, and on the right in "D" from up to 8d, since the postal rate was one penny per half ounce. Now, as an antique, a good specimen might auction for up to £500.[Image: a detail is inset, with a red mark added to highlight the scale pointer.]
