I recently bought a collection of silver mugs and decided to start of a collection. Although I've been able to identify most of the silver marks on the mugs, I have one mug which I don't know the marks from. I hope anyone can be of assistence. The pictures are below


The first mark looks like a diamont shape with A 800 in it, the othe one looks like a D and a W.
thanks in advance,
