Help with maker

[doveplace]

Hi, from the marks I determined that the pin is 833 silver and that the 78 corresponds to 1878. I wanted to make sure that those assumptions were correct and also to see if anyone knows what the castle mark and makers mark could be. Thanks!

Hi,

Norwegian silver and MH could be for: Marius Hammer(1847-1927), city of Bergen ( seven dots for the seven hills).Hopefully another member will confirm/deny.
