Scales and Weights

Scales

1. English equal-arm hand scales with swan-neck beam-end used in 18/19 century dispensing. Brass pans 6.5 cm. diam.
2. Bench dispensing scales, W. & T. Avery & Co., made between 1818 and 1850 (see letter from L. Sanders, Avery Historical Museum).

Weights

1. Set of nested brass Troy weights, 8- ounce to ¼ ounce. As 19th century critics often remarked, such weights were subject to wear and tear and, what is more, rarely stamped and inspected.
2. Ditto, 4- ounce to ¼ ounce.
3. Ditto, 2- ounce, ½ ounce, ¼ ounce.
4. Coin-shaped 2-drachm weight issued by W. & T. Avery and registered on March 16, 1847. Such registration gave protections against production by other manufacturers for three years. An important feature of the weights is that their denomination is denoted both by symbol and by word.
5. Rimmed, lozenge-shaped 6-, 5- and 4- pennyweight Troy weights. Reverse marked with appropriate number of punch marks.
6. 4- pennyweight Troy weight with lion stamp. Reverse bears crowned Royal monogram V R with bird emblem and stamped J10 and 2.
7. Square pharmaceutical weights with rims (18th-19th cent.)
   • (a) ½ scruple
   • (b) 20 grains, 1 scruple
   • (c) 30 grains, ½ drachm
   • (d) 2 scruples
   • (e) 60 grains, 1 drachm
   • (f) 2 drachms.
8. Square, 2- drachm weight with bevelled edge (18th-19th cent.).
9. Grain weights, comparatively rare with denominations denoted by numbers: 2-, 3-, 4- and 5- grains.
