I have what I believe to be a 7-1/2" tomato server that seems to be coin silver, but is unmarked. The handle is very pliable, so much so that it seems the narrow part of the handle would barely support the weight of a slice of tomato. There are no maker's marks, except for the three large letters acting as the open part of the blade -- FHW.
A search has turned up only one manufacturer that I could find using those letters -- a German maker Franz and Hermann Wandinger. I am somewhat skeptical, however, on this, being they made silver and gold items for Adolf Hitler's third reich. I would think their items would have a maker's mark.
