Salt Glaze Success Filter, top half

Question:

I am hoping to get possession of the success filter in the attached pic and wondered if you could help me with some detailed information and market value.

Again, thanks for your assistance.

Answer: This is the top half of a salt glazed success filter made in the late 1800’s by Red Wing.  A complete set sold at auction a couple of years ago for $2200.  Your piece, by itself is valued around $800.
