No problem dear Zolotnik. The mark is JR&S i.e. Johan Rönnqvist & söner (sons) in Örebro Sweden 1895-1907(1927). Your cups are made 1910. Johan Rönnqvist was born 9.11.1856 and he died 9.11.1935. He worked in Piteå in Örnsköldsvik, in Örebro and in Denmark in Askersund 1881-1885. Then he moved back to Örebro in Sweden in March 1886. There he founded a company in cooperation with F. Söderström 1895-1907. In 1908 his sons Paul, Ivan and Elof took over and they marked until 1927.
