Will you please help to identify this decorative flatware set? The spoons and forks are approx. 4.5 inches long, with brightcut etching. I bought them a while back from an eBay seller who said they were from Holland. As far as I can tell, they show strong signs of Javanese/Indonesian Yogya-style influence.
The marks on the back appear to read "POB", with an additional sword-like mark.
I'd like to know the maker, and the silver content if possible. Thanks in advance for your help!
