Newark Silver

Today I bought what I thought was a brass gravy ladle, but on close inspection I found that there was a small area that still had silver plating on it and the mark on the stem read Newark Silver. I’ve searched and can find nothing on Newark Silver. The ladle looks as if the handle may have been hand welded to the bowl. Can anyone tell me more about this ladle and when Newark Silver may have been in business and where? Thanks.
