Danelle,
These all look to be of the same mold and maker to me.
My sugar measures 4" in height but across the handles is 4 3/4". You may want to remeasure. The creamer to the top of the handle is 3 3/16".
The Dogwood pattern is so very close to mine but some of the flowers appear larger.
The decorator who applied the polychrome was very skilled. It was so well done.
You are an excellent super sleuth !!
