Identifying headjoint makers mark

[jadriaso]

Hi, I'm new in the forum. I just bought a bashed Miyazawa flute to restore, and it came with a silver headjoint by some other maker. Have any of you ever seen this mark, know the maker? https://www.dropbox.com/s/eq4gwerf1qoos ... t.jpg?dl=0


Thank you all in advance
