Context (Analysis)
Cf. London Museum Medieval Catalogue Plate XXXI, especially nos. 53-58 - a variety of Type VIIB keys from London. Type VIIB keys with 'kidney-shaped' (i.e. cusped) bows are reportedly characteristic of the 15th century. As such, the Period field has been changed from 'Medieval; 14th century; Post Medieval; 15th century' (as described in the accession register entry) to 'Medieval; 15th century'.
