Nickel Silver Spoon

Bought this spoon this weekend

I assume NS = Nickel Silver
But who are Ö & LN?
And what is written in the middle?

 

Stockholm maker Östberg & Lenhardtsons Nya AB, dating with 'Nya' (New) is 1915-1933, but the firm was in business as Östberg & Lenhardtsons prior to that, I can't make out the next couple of marks, though I feel I should know them (might be a Stockholm St. Erik head there), 'PRIMA' is an indicator of quality of the plating, 'NS' is Nysilver, nickel silver typically silverplated, '14GR' for the amount of silver used to plate a certain amount of pieces. The pattern is a classic old Swedish pattern called 'Gammal Fransk' (Old French).
