Help Identifying Antique Sterling Hallmark

Need help identifying hallmark, please see pics, its a potpourri bowl, I  believe its American Sterling or Meriden Britannica.

Does look like a worn Meriden Britannia mark. (Not"Britannica")

See example and more company info here: http://www.sterlingflatwarefashions.com/Silversmiths/SSM6.html
