Mysterious Russian bronze (if that, for sale ...)

[AlexSpb]

Well , actually, all in the subject header ...
" Curious ," this thing is , of course , first and foremost for me. Specialists believe right now, all told. Like, all the letters of the author's name is quite readable, although the options have different interpretations . Something like " Lyufferd ", but such is nowhere found ( by the way, here is where the photo caption is better than life ). Search by name immediately gives " Sculpture of Radziwill the Orphan " and nothing more ...
My own views on the part of the search for truth in this exhausted.

Height -26cm , weight decent ...
