The hoard which has given its name to the type was found in 1735 on Arreton Down in the centre of the eastern half of the island. Part was exhibited to the Society that year and a further ten pieces in 1736, drawings being made of the last exhibit. In 1855 Mr. A. W. Franks (later Sir Wollaston Franks) described in detail the hoard as then known, i.e. six pieces in the British Museum and the remainder recorded by the drawings made in 1736 (Archaeol. xxxvi, 326–31). In 1909 the well-known socketed spear-head and a tanged one were acquired by the British Museum from Canon Greenwell's collection. The hoard consisted of ten spear-heads, two daggers, and four flanged axes. They are referred to below as ‘Franks, no. —’; ‘B.M.’ if in the British Museum, ‘D’ if now known only by a drawing.
