Can you identify this Edinburgh maker?

[Scrabble96]

I have a silver butterfly brooch and have managed to work out that it has an Edinburgh hallmark for 1985. What I can't fathom is the maker's mark. I've Googled the image with Google lens and an identical brooch came up with Malcolm Ortak as the the maker, but the mark doesn't look anything like MO.

Any help gratefully received.

Hi,

I think the mark may be 'MG'
