vintage hand blown art glass artist signed swung glass vase, pink cranberry glass

Great big swung shape on this vintage cranberry glass vase - it measures about 12 1/4" tall.

This is hand blown, with pontil mark on the bottom. It's signed by the maker, C Williamson (I think?) I couldn't find a Williamson in the West Virginia glass records I checked, though this looks like a Pilgrim glass or Fenton piece to me.

Condition is excellent, no damage.
