I identified this mark five years ago. As promised, I'm searching my inventory for the identification. It's a slow process; I list only the name of the maker and description of the piece, but no description of the mark. If an item looks promising, I must go to wherever the item is in the house and look at the mark. With over 1,500 silver and silver plated items, it's a slow and painstaking process. I do remember that the key to the identification of this mark is "L" over the lion. It's a veritable treasure hunt and I will post the identity as soon as I find it.
