WW1 Imperial Russian military button, large 22mm size. Great condition nicely maker marked.

This brass button features the Imperial Russian double-headed eagle emblem, confirming its origin in the Russian Empire before 1917. The backmark “ВРВУЗТ” (transliterated as V.R.V.U.Z.T.) appears to be a Cyrillic maker’s mark from a St. Petersburg-area firm producing military uniform buttons during the late Imperial era. It dates to approximately 1890–1917, aligning with World War One usage.
Maker Details
ВРВУЗТ likely stands for a partnership or factory initials, such as “Варшавско-Рижско-Виленское Устройство Знаков Тканевых” or similar, but records are sparse; it matches patterns of Imperial button makers like Brothers Bukh (Братья Бух) in St. Petersburg, who supplied army buttons from the late 19th century. These firms stamped Cyrillic abbreviations on reverses for authenticity, producing high-quality brass items for uniforms.
