Qrt.S A samovar's drip bowl in silver...hmmmmm!?
Yes, we are always suspicious when something rather uncommon emerges.
But there are sugar bowls of this form (cахарница) and when the handle is badly damaged and beyond repair, or missing, the easiest way to transform it into a lucrative and marketable object is to remove hinges and polish the rim.But that`s difficult to tell based on pictures.
In short, beware of rare Russian pieces, uncommon and seldom seen.
