Recycling in HK

Took this picture at the UK National Archive (their ref: WO 78/5341), showing that recycling is not a new experience for HK. It is from a plan of part of a gun pit for a 9” RML gun at Stonecutters East Battery, which was built in 1881. The pivot for the gun is an unfortunate 24 pdr muzzle loader, obviously obsolete by then. Murray Bty was the only one in HK that I know of using 24 pdrs, but they were quite common in warships earlier in the century, so its history is obscure.
