Troy, it seems you have some interesting items here. In order for anyone to give you an accurate assessment of them we need to be able to see them clearly.
The top items are ewers but you will need to supply better pictures (bottom with maker's marks and inside) as well as the size of them.
The second picture appears to be silverplate and could be a water pitcher that was previously with a water/goblet set OR a coffee pot with a creamer/sugar? Need a larger picture of each as well as makers marks on the bottom. Will also need sizes.
The third item does initially look like a pickle castor but, as the items before, we need better close up pictures and pictures of the bottom of the stand to verify maker. Would also need to verify that the lid goes along with this or was added later. Also need size.
The final picture needs more pictures, listed sizes and makers' marks as well.
As you can see from the replies, folks here on the forum are eager to help, just need more information in order to do that! Looking forward to more information!
