I need information about the producer and the period of creation
Thank you

Hi,
The only S&K in Malmö was Sjögren & Komstadius Aktiebolag, active in Malmö between the years 1928 to 1964.
Y in date letter is clear, therefore it could be 1949.
The technique is called samorodok in Russian, meaning that the metal is in its pure or natural state found as nuggets.
This result is obtained by heating silver to a temperature near the melting point and cooling it abruptly in water.

Regards

The year mark is X8, so let's reduce one year 1948.

Qrt.S is right about the year, it is 1948. (X8)
Have a nice evening
