Zlatust is a Russian town known for over 200-year heritage of hosting master engravers and decorators. In 1991 a company called Praktica was established in this town. A team of local master engravers has joined the newly founded company and since then they produce a number of precious metal plated and engraved items including firearms.

The processes used to decorate these firearms include nickel plating, etching, blueing, enameling, gold plating and so on. The materials used in the process are brass, silver, gold etc.
The company also makes such decorated versions of many other firearms (mainly Russian ones). Images of some of them you can find below.
The master engraver of these firearms is a gentlemеn named Oleg Averkin with the exception of the PSM pistol which is Vyacheslav Tychkin’s work.
