This pattern of Crown, its quite distinctive in design, shape and manufacture, was worn specifically by the Metropolitan Police pre. 1953 as a rank badge for Superintendents etc. I've never seen an example with that fitting, nor can I say who would have worn it. Presumably intended for wear on a cap?
