Maker's mark is CE (I presume this does not signify EU reg conformity :P )
Assay Mark only appears on bottom half of the piece and strangely is upside down, appears to be AM.
Sold (and manufactured?) by Nicholls & Plincke, St. Petersburg.
It was a gift to a foreign ambassador to Russia (who's monogram is etched on the lid).
I can't find any information on maker CE and am unsure about my assumption regarding the city mark. Assay mark I take to be that of Aleksandr Nikolayevich Mitin, which also fits with the known date range for the piece. There also appears to have been an attempt at a stamp below the assay mark, which I assume may have been the year?
Any thoughts on this would be very much appreciated.
