Help needed from Swedish silver experts!

I have recently acquired a ladle with Swedish hallmarks, as shown in the accompanying photos - about 38cms. long and weighing 258g.

The hallmarks show the maker ‘Mollenborg’, the town letter ‘F’, the Swedish Three Crowns mark and ‘N5’ for the date year, 1867.

Can anyone answer the following questions:

  1. Is the town FALUN? (This is the only F I can find in a rectangular cartouche.)
  2. I cannot see a hallmark for ‘S’ but is this piece most likely to be 830, or could it
    be 925 standard?
  3. Is Mollenborg silver highly regarded, or run of the mill?

Answers to these questions and any other information gratefully received!
Many thanks,
Peter
