Excellent condition, silver plate is wearing off a bit. Rik was founded in 1895 in the city of Dolne Hamre in the Slowakia region of what was then the Austro-Hungarian empire. It rapidly grew and employed several hundred workers. It closely collaborated with another company, Krupp-Berndorf in Austria (actually Krupp owned a lot of the Sandrik shares until the early 1920ies).

Sandrik cooperated in the 1930ies with well-known designers like Ladislav Sutnar and Bohumil Juznic.
