Embossed steel. Embossed outside. Beer. Zhigulevskoye. Production period: 1913-1914.
Inscription on cap: "Жигулевское пиво" around, in the middle VF in triangle.
The brewery sign in the middle is under 1924. It's hard to identify the period, likely it's from early USSR or late Russian Empire.
It's the oldest crown cap from Russia!
