vintage sterling silver demitasse spoons w/ guilloche enamel, marked Norway

Five vintage sterling silver spoons with colored enamel, each spoon handle a different color.

These are 4 1/2" long end to end, marked as shown. (I'm not terribly familiar with Scandinavian silver marks, sorry!)

They're a little tarnished, but otherwise all in very good condition, the enameling looks perfect.
