Scandinavian Sterling Modernist Ring, Maker "OD"

[volpone]

I'm hoping to find out who the maker is on this sterling modernist ring; I found one "OD" listed as a Danish maker active in Copenhagen until 1937, but I thought the design of this piece would be likely a bit later than that?

Thanks for any ideas!

Hello.

That's probably Ola Dahlsveen of Trondheim Norway.
They might still be in business, not sure.
