The initials HY which appear on certain pieces of Kelantan silver have been a mystery for some time.
See https://www.kraftangan.gov.my/en/craft- ... -craftsmen
This concerns a skilled Malaysian silver smith, Allahyarham Tuan Haji Ab. Manan Bin Haji Yakub (Pok Teh), who has been designated a Master Craftsman.
In the second paragraph it reads
"As a child, he often watched his father's craftmanship work, the late Haji Yakub bin Mohamad, who was a skilled silversmith crafts for British officials besides receiving orders from the palace."
Haji Yakub died in 1977.
Could HY be Haji Yakub?
