Set of cutlery with two hallmarks I cannot identify...

I have been trying to figure out where these were made and by whom but, quite unsuccessful. I just need some help indentifying the maker and year of items on photos I’ve enclosed.
Any assistance would be appreciated.

I’ve just got info that the marks are from Portugal. They indicate the second standard of 833/1000, Oporto assay, and were in use from 1886 until 1938.
One of marks present ‘wild boar head’ the second one is unknown to me.

I hope that someone can identify the maker.
