The discovery in 1719, at Brough-on-Humber [North Humberside, SE 93 26], of a hoard of Late Bronze Age weapons and casting matrices is described from contemporary manuscript and printed sources. The subsequent passage of its component artefacts through antiquarian collections is carefully documented, and four pieces are recognized as surviving in the British Museum. These comprise two rare two-piece casting moulds together with one example of each casting product. One mould is a Welby, the other a Meldreth, type, formerly provenanced respectively to ‘Yorkshire’ and ‘Quantock Hills, Somersetshire’. All are described in detail and suggestions made as to the casting techniques in which they were employed. The hoard, possibly originally comprising more artefacts than were recorded, was accompanied by a spearhead, a socketed chisel and a tanged awl or spike, now lost. These are attributed to Burgess's ‘Ewart Park phase’ of LBA2, with parallels scattered throughout the north-east, east, south-east and south of England.
