I put these two together as they have the same theme.  The vase is 6" high, 10" round and the mouth is 3 ".  There is an weak initial on the bottom which I can't see.  The butter dish top is from Johnson Brothers, made in England.  I received the plate to go with it but it is chipped and will only add this if wanted. I know I have butter plates with no cover so I think this might fit any of them. Here is its measurement  8" by 4 1/2".  The top measures 7 by 3 ".
