This key is of ‘lever lock’ (or rotary) type and is attached to a chain used for suspending or carrying the key.

The area of the handle close to the stem is decorated with lines forming a saltire cross set within grooves to all sides. The key ‘handle’ is rectangular and the terminal (bow), which is perforated for suspension, pointed.

A butted ring passes through the bow connecting it to a chain of which three links are present. The chain is of single loop in loop type, formed of rectangular-sectioned strips.
