A cast copper-alloy key of the Anglo-Saxon period. The bow is discoidal with openwork in the form of a quincunx of small circular holes. It has a transverse suspension loop, 5mm in diameter, at the top. The shank is of sub-circular cross-section, 18mm long x 6mm diameter, and has a 3mm deep pipe end. The simple bit is of the usual long, slender shape, and projects at right angles from the shank in the same plane as the bow. It is 11mm long.
Nigel Mills (see References below) comments that "After the Romans had left Britain, the use of bronze keys did not reoccur until the 8th century."
