Visible Markings: 297 on right trunnion, GR3
Material: Cast Iron
Remarks: The 24-pounder long gun was a heavy calibre piece of artillery mounted on warships of the Age of sail, second only to the 36-pounder long gun.
Four lengths of iron 24-pounders are mentioned in Thomas James’s 1722 notebook: 10 ft (3.05 m), 9 1⁄2 ft (2.9 m), 9 ft (2.75 m), and 8 1⁄2 ft (2.6 m) long.
The length of this barrel measures 9 feet and its bore diameter is 5.823 inches.
In the land service, the 24-pounder, especially the heavier gun, was highly regarded as a battering piece, and it was extensively used during Wellington's Peninsular campaigns and again in the Crimea some 40 years later.
The Blomefield pattern design means that this gun was cast after1787 when the Blomefield loop cascabel pattern was adopted.
The right trunnion bears the serial number 297. The breech area is heavily encrusted with concrete when it was embedded at Ragged Staff before being removed to Hay’s Level.
