It IS pretty with a very strong Damascus pattern to the barrel and nice stock wood.
It is Belgian - the ELG proofmark has been used there for a LONG time.
It is kind of hard to say more besides what you see is what you get but there is not much to know when the maker does not put his name on his product.
Maybe the J I N signifies something, but nothing I have seen.
It is likely a "guild gun" assembled from parts made by small independent shops and therefore with no real brand name.
