6 Spoon Set Need help identifying

Can someone please help in identifying these marks. I have not been able to find anything similer on the web.

ABD F (maybe a crown) S M9

Thank you

These are Swedish marks (the “crown” mark is actually 3 crowns but has not been well struck). M9 is the date code for 1962, S in hexagon indicates 800 standard silver and F in circle is the town mark of Falköping. ABD, the maker, is listed as Brofod Aktiebolaget of Falköping.
