Sheridan Dolphin footed silver plated on copper 4-piece tea and coffee set with tray. No markings that I could find.Jack Shepard Holloware is a possible match too. This set was inherited from my grandmother who is now deceased, so I cannot ask for more details. This is purely through my own diligent research.
The pieces are tarnished, but I will not risk damage attempting to polish them. Price set at what current fair market states for this set and condition. If you have more insights into this brand and pattern, please message me.
