Little metal lidded potpourri / perfume jar

Funny little thing I picked up at Newbury fair.

Lidded potpourri jar. Soldered wire and cut sheet panels with enamel decoration (possibly paint or chalk filled, rather than glass enamel, as it's discoloured from white to cream).

Name of perfume manufacturer on the base - Perfumer J.N. Taylor London. - apparently Taylor of London was established in 1887 and is still going.
Still smells strongly of perfume. Appears to be 1910-20 era.

Not sure of the metal. Seems too lightweight to be silver or copper alloy. It's more like spelta, but I'd have thought spelta would be too brittle for wire. Tin, maybe? Pierced panels might have been cast before being soldered on a wire cage. Shiny metallic-white on the part of the rim that's rubbed by the lid.
