Silver plate hallmark identification help

Can anybody give me any information on this piece? I did a google search and low and behold I found my exact sauce boat, or so I thought. It is identical but the hallmarks are different. Did different makers make identical pieces? That is what is confusing me about this. Again any help with anything about my sauce boat would be greatly appreciated. The first two photographs are from the item I found on the internet and the second two photographs are my item.



Your sauce boat has the mark of William Marples & Son and the one you found on the net is Marples & Co, both based in Sheffield. I am not sure exactly how the 2 companies may have been related but clearly there was some sharing of designs.
