Enamel Silver Spoon Hallmark?

Hi All,
I have recently discovered a set of spoons from my late grandfathers loft and I am unsure of the markings and what they represent in terms of maker. I am pretty sure they are not English and that the spoons are 925 grade silver. The S & Mark are unusual though?

Any help will be most appreciative.

Thank you in advance

Looks Norwegian, but unsure of the maker’s mark. Appears to be similar to Marius Hammer of Bergen but not an exact match.

Hello thanks for your reply, I have since found out it is Norwegian and the maker is David Andersen. The hallmark dates them back to the 1920’s - 1930’s
