Double key consisting of an ordinary rotary key and a socket key of the Bramah type. The bow of this Bramah key is formed by two facing C-volutes, which terminate at the top in an onion shape and enclose a small ball. The keys were probably joined together at a later date. The Rijksmuseum, Amsterdam, holds this object as BK-KOG-2307; its record gives material recorded as iron (metal); measurements length 11.8 cm x width 4.2 cm. Description translated from the museum's Dutch catalogue text; details are those of this museum object, and how far it represents a wider type has not been independently verified.
