Hello from a new member and greetings to everyone - am lucky and honoured to come across this forum.

I recently acquired a keris and had a new sandangan branggah made for it by a senior mranggi from Ponorogo. He gitted the sandangan with a perak lamen (old silver) pendok and I noticed there's a crown engraving at the back which piqued my curiosity (the attached picture).

Have any of you come across similar engraving before and does anyone know what does it signify/represents?

Thank you in advance for kindly and generously sharing your knowledge and wisdom.
