Engraving, possibly made in 1746, showing a scene in the Exchequer at Westminster during the reign of King Henry VII (1485-1509). Henry's Exchequer, or treasury department, created new standards of measurements for merchants in the late 15th century and subsequently sent standard weights to 43 English shire towns.
