Oriental ginger jar lamp signed black ship ?

I bought this lamp last year and today I had taken the wooden bottom off to see if I could find a makers mark and boom there it was but I don't have a clue who this is by

Its a very large lamp and heavy it used to be a ginger jar as the lid can come off when the wooden bottom is loosened off

The design looks to me as the black ship that sailed from holland to japan back in the day and this is heavy ENAMELED

Any help would be appreshiated
