Please could someone help to identify the marks on this samovar?
I have been told that it is possibly Portuguese however can't seem to find any marks similar.
Marks appear to be a boars head and another animal which appears to be leaning over?

The first of the marks does not look good, it may be a "J" ???. The second brand belongs to the silversmiths "Silva & Martins" from Porto, registered in 1915 and disappeared in 1936.
