Description: | An almost complete copper alloy surveyor's tag of Post-Medieval to Modern date. The tag is flat with an integral though broken suspension loop projecting from the outer rim of the upper curved edge. The main plate is sub-circular withtwo V-shaped recesses from the lower outer edge extending towards the centre resulting in three rounded "teeth" facing downwards.The metal has a mid green patina and is worn. The object is 42.3mm long, 31.4mm wide, 3.5mm thick and weighs 22.5g.Numerous similar examples have been recorded on the PAS database, for examples see: KENT-31E9F4, LANCUM-2DAF93, LANCUM-E57545, SUSS-402DE5 and SWYOR-2F7CF1.BUC-EED724 states that the surveying chain was first recorded by Edmund Gunter in 1579 and examples such as these would not have pre-dated 1620. The surveying chain was marked at every 10 links by tags or tallies; at 10 links a single pointed tag, at 20 links a double pointed tag and so forth. These chains were based on an ancient measure of the breadth of a furrow or plough strip. A chain composed of 100 links is 66 feet, the exact measure between the stumps of a cricket pitch and it was also used to measure this. The invention of the steel tape in 1867 brought this method of measuring to a gradual close.
