So I got my hands on something very simular.
maybe Truls J Tonsberg can help me out here as well.
Its some sort of serving plate with 1861-1961 on it and a Norwegian flag with (crown) Post on it and the letter W.
The W could be Wilhelmsen founded 1861 making it a one year anniversary plate.
But what is the connection to the Royal Post?

This is a cup/Prize that is used for prizes in sports etc. They are not used for anything other than standing in a prize cabinet/On the prize shelf. The letter below is a designation of the size of the cup. A is Largest. In Norway we use 830s and the firm's logo/Maker's mark. And often N in an letter for Norwegian design. I have worked at TH Marthinsen for 16 years. When i was young :)
Best regards.
