Hi.

This beautiful small silver egg was made in St-Petersburg in 2000. New Russian punch of the 925th silver since 1994.
Maker mark is Л0УE. "Л" - the North-West assay inspection (Leningrad-Petersburg ). "0" - 2000. "УE" - an individual code of the manufacturer. Who is he I don't know, unfortunately. At that time there were many private workshops.

Best Reg..

Л0УE is "Художественные Мастерские Федорова г. Санкт-Петербург"

i. e. "Art Workshop of Fedorova in the town of Saint Petersburg". Dad has told you the rest.
