Mind my saying dear silverport, but this "rabota" mark was the first legislative attempt the bolsheviks made to establish a new Assay Charter after the revolution in 1917.
In 1927 the People's Commissar of the USSR, citizen Briuhkanov ratified the new set of rules concerning hallmarking of precious items in USSR. This "rabota" mark was used as from 23rd of June1927 until a new assay mark, the Soviet Star with the hammer and sickle inside, was was developed on 7th of May 1958. However some minor changes happen as from January 7th 1954.
In order to know when the object in question is manufactured,we need to know what number(s) follows the letters МЮ. It looks like only one figure but what?
Of course it could be from the period 1954-58, but it's up to the figure(s) to show that.
