Additional information

The case is English made, double backed and triple hinged, with Birmingham Hallmarks for Sterling Silver, 1933/34.

Also has the maker’s mark of Dennison who bought out Benson Brothers (no relation to J.W Benson) in 1933/34, meaning they now had a long term contract to supply J.W Benson with cases from 1935 onwards. In general they reverted to using the Benson mark.
