Hi,

It's silver-plated. The maker was Alexander Katch, a German, who set up a factory in St Petersburg in Russia in the second half of the 19th century and was in business there until at least c.1910. The 'GP' stands for 'Galvano Plated'.

Hi,
No appraisals here. It`samovar used to heat and boil water for tea.
There are many examples online.
