Featured Can you help me Identify this Bloodstone Scandinavian ring?

Can anyone help me identify this ring? I have worked out that its Sweden 1968, but thats as far as i have got, does anyone know the maker ESm or the R City mark? or maybe its actually a H? that would make more sense for Falköping but it does not look right.

PS. click images for much larger photos.

 

The town mark looks like a B in a circle to me. That is the mark for Borås.

 

Thank you! your search term Borås found me a completely different set of results than my google searches, its Hvetlanda (now Vetlanda) and the maker is Svedboms Guldsmeds Ab Hov.

 

Good search. I see it now, the top bend of the h looks connected to the part below, so it looked like a B. But you are right, Hvetlanda, with the little curl bottom right.
