The history of this furniture is, that my grandfather in ***0 bought it in Moscow from one of the employee of Hermitage Museum, who said that this furniture belonged to Napoleon Bonaparte. He said that, some of this metal was restored and others not. 

I reviewed photos of Napoleon Bonaparte`s furniture by the internet, and some of them was similar of my bedrooms ornaments. As I know, the material from which was made this furniture, is rose tree. In any case, these furniture is to date from Napoleon III period, rather than the 1st Empire.
