Vintage Sheridan Silver Plate Ice Bucket w/Maker's Mark

This is a lovely footed ice bucket with the Sheridan maker's mark (Crown, S, and Shield) on the bottom. It also says "Sheridan".
It has what we think is a porcelain container inside with what appears to be cork insulation. The hinge is intact, works well, and the lid stays up by itself.
It is tarnished so we did not polish it.
T is no reserve.
It is heavy, so shipping is $14.00 anyw in the U.S. via USPS Parcel Post.
Hats off to the USPS for raising the rates sky high.
Please email us for additional pictures or information. Thanks!
