Pin possibly from Sweden? Several marks, SOLDOR?

[dm4043]

This heavy pin has SOLDOR with a copyright symbol in the middle. Then in the middle of one of the spirals there is a series of marks
S.D?, elegible mark, 925, and what looks like a control stamp for 1975 Sweden. They are so tiny.

Hi,

Welcome to the Forum.

I believe that would be SolD'or, a trade mark belonging to the jewelry company, A. Hill & Co. of Birmingham.
