Mysterious Norwegian Silver Container

I have acquired this piece recently and I am trying to determine what it is. I think I have narrowed it down to being a biscuit jar but only becasue I have found other items online that seem to have a similar shape.

The markings on the bottom indicate it is from Odin Domaas (O. Domaas), a Norwegian silversmith from Trondheim. It also indicates .830 Silver (830S). The word "Handarbeid" (I believe this may be handmade or handcrafted) is stamped in bottom as well along with the numbers 6086A.

My internet searching has led me to believe that his piece may have been made before 1920 as Norwegian silver was .830 prior to that time and often .925 was used after.
