Post Medieval cast copper alloy trade weight from the 18th Century. The weight is circular with a wide raised rim on the top. It is 35mm in diameter by 4.35mm thick and weighs 25.72 grams, 0.9 oz (equivalent one ounce). It is stamped with: Crown (The sword of St Paul on a quartered shield - the City of London Guildhall mark, from 1826) at 11 o'clock; The sword of St Paul - the City of London Guildhall mark, pre-1826 at 1 o'clock and an ewer (for the founders company) at 6 o'clock

A bell-shaped one-ounce trade weight of the mid 19th to early 20th century. The weight is stamped on the face of the handle with its denomination. The top of the handle is stamped with an X, possibly a cancellation mark. The classic ’bell’ weight was popular with butchers and grocers.

A half-ounce copper-alloy trade weight, probably made during the reign of George III or the early years of George IV, showing the following verification marks: 1. Crown over ’G’ - the royal cypher (4 o'clock) 2. The sword of St Paul - the City of London Guildhall mark (12 o'clock) 3. A ewer - The London Founders' Company mark (6 o'clock) There is no ’A’ for Averdepois, which is often the case with weights of one ounce or less. Attribution to the particular monarch (George I-IV) is based on the relative positions of the marks. The arrangement on this weight was used under George III (1760-1820) and the early years (1820-1826) of George IV's reign.

Smith & Co., London. William Smith & Co., London. Wm Smith & Co., Borough, S.E. W. Smith, Borough.
William Smith was a London scale maker, working c 1802-47. The name (William) Smith & Co., London appears on weights with pre-1865 verification marks. The address is given as 'Borough' (a street in South East London) from c.1870 onwards. By 1905 the firm seems to have been merged with Gilbert& Co, and Doyle & Sons. A coin-scale label of c.1830 describes Smith & Co. as successors to Dutton and Smith. The address was 238 High Street, Borough.

A quarter-ounce copper-alloy trade weight of the Victorian period, showing the following verification marks: 1. A ewer - The London Founders' Company mark ( 6 o'clock) 2. Crown over ’V’ - The royal cypher of Victoria (2-3 o'clock) 3. The sword of St Paul on a quartered shield - the City of London Guildhall mark, from 1826 (9 o'clock). From about 1850, most weights were marked with their value at the time of manufacture. It is likely, therefore, that the present weight dates to the period 1837-c.1850.
