The find consists of 8 iron nails and an unidentifiable object that contains one further nail and is made of, or covered in, what appears to be fur. The nails range in length from 135 - 175 mm, and c. 10 - 20 mm in width at their widest point below the head. All 8 nails have a rose type head and taper to a broad point. These features suggest that the nails were hand wrought, rather than cut or wire, a method where each nail is manufactured individually by hand on a blacksmiths anvil. The invention of the slitting mill c. 1590 simplified this process by manufacturing iron rods from whi…

This item appears to be a small calibre black powder weapon, such as a swivel gun, commonly mounted on vessels throughout the age of sail as well as being used in terrestrial settings. The weapon is approximately 750 mm in overall length, with external muzzle diameter of approximately 110 mm flaring to an external diameter of 180 mm at the breech end. The condition of the artefact is poor due to heave concretion, though visual analysis suggests it is a muzzle loading gun. No Trunnions for mounting the weapon are immediately apparent despite the concretion. As their name suggests, swiv…

Double edged blade covered with concretions, around 25 mm wide and 280 mm long. Displays iron oxidation, and the item has not been preserved well. The blade is roughly 200 mm long and the thicker handle is approximately 80 mm long. Following consultation with Henry Yallop of The Royal Armouries museum, this object can only be discribed as roughly the shape of a common blade form , i.e. roughly lenticular, and about 25 mm broad. What is not clear is whether it was once the complete blade, or that this is part of one, or alternatively that it was the part of another forged object, and o…

This is an assemblage of six round cast iron and stone projectiles of varying sizes. Due to the ubiquitous nature of their design, it is difficult to accurately date cannonballs with any certainty. This issue is compounded by the wide variation in designs and calibres of the cannons that fired them and the lifespan of the weapon, with obsolete designs often still in use on merchant ships long after they had fallen out of service with the various navies of Northern Europe, who also used captured weapons on their vessels. Cast iron cannonballs are thought to have appeared at some point d…
