Could this be a 18th century French mustard-pot, region Dijon Communautés ... or fantasy marks?
The mustard-pot with a plain baluster body and C-scroll handle with shell-shaped thumb rest, gadrooned and beaded borders. Inside a pewter liner.
The three marks at bottom base; Asclepius, W under treetop (?), Crowned town crest.
All information welcome, thank you in advance.
