Highly figured Pickle Fork maker?

I am attempting to establish who the maker is for this fork, perhaps a date also?
It is marked 830S followed by LO, then NM, then Nr.492. Length is 5.3/4ins
Thank you in advance![/img]

830+S tells you that it is silver and than content of silver is 830 parts of 1000.
LO is maker Brødrene Lohne (Brothers Lohne) they are fom Bergen.
NM is Norsk Mønster (Norwegian Pattern)

nr 492 that must be a product number possible name of patern?

Typically norwegian in look etc.

Thanks for the information I appreciate it. :smiley:
