Nobody?
The marks PRÖVE, PRØVE or PS are actually Danish marks implemented in the late 18th century. At that time Norway was a part of Denmark (in union). In the middle of the 18th century it appeared that the goldsmiths used mainly below-standard silver. The minimum legal standard at that time was 13½ lot (since 1608) but most of the made silver objects' fineness was only 12L or even less. The big bang happened in 1762 when the guardein in Christiania (Oslo) himself was caught using below standard silver. Also many goldsmiths were caught in using "poor silver". All were punished and fined. Something had to be done but the authorities were unable to do anything.
For obvious reasons the people had lost confidence in silver objects. The situation was a mess. Goldsmiths of the Chrstianialaug (Christiania guild) in Bragernes and Stromso¸ (later the town Drammen) with surroundings located on the western side of the "Oslo fjord started to use a fineness mark "CL" (Christiania Lauget) in order to guarantee legal fineness and did not use the ordinary series of marks master, town, guardian and fineness. All in order to retrieve the people's confidence. About the same time alongside with the CL-mark these PRÖVE, PRØVE or PS marks were implemented in the same region and also in villages around Skienfjord. These marks guaranteed a minimum fineness of 13¼ lot. It was not until the year 1820 when the minimum was stabilized to be 13¼ lot allover the country. However, a lower fineness could be used but the fineness had to be punched on the object. In 1814.
FYI, Norway became a part of Sweden (to 1905).
In Copenhagen the goldsmiths as well started to use a similar mark; "Pröve" and "KHvn" i.e. "Københamns prøvesølv" meaning Copenhagen's tested silver.
As Torsten already mentioned the marks PRÖVE, PRØVE, PS, Pröve or KHvn are not official marks because they are punched by the maker himself and not the guardian for reasons told above. The marks were abolished shortly before 1850.
Long review with many words and history but this was how it happened.
