HI , this reply is several years too late but I have found this item in a james deakin catalogue that I own.
The item is actually a “sugar scuttle” ( I have one that belonged to my grandmother.
The original item was sold in both E.P.N.S and E.P.B.M. The first costing one pound ten shillings and sixpence. The second sixteen shillings and ninepence.
