These are three links of surviving Mauretania anchor chain (and my arm!) They have the date on them, '1906' (the chain, not my arm). Each link is 130 lbs / 76kg. At the time it was the largest chain ever made for an anchor chain. Length was 1,900 feet / 579 metres, total weight was 132 tonnes. Made at Brown, Lenox and Co. chainworks in Pontypridd.
