This is not my item; I have pics only, so I cannot tell more. I posted it only for the sake of better understanding how silver behaves under different conditions when exposed to chemicals or polluted air. Still, I have never seen red patina on silver, it turns red only when tested, but that is a different situation. The craftsmanship is poor, I agree.
Regarding ``kokoshink`` with delta (1908 — 1926) the exact description is: ``МоÑковÑкое пробирное управление, нижегородÑкии и тульÑкии губернÑкие пробирерьи`` (Meaning that delta was used for assaying in Moscow, Nizni Novgorod and Tula). This is of less importance, but good to know; the point is that silver cannot tarnish red under normal circumstances.
By the way, without opening a new post this is the answer for the previous discussion I noticed reviewing earlier posts: The picture tells more than I can comment and the book is Russian.
