Silver Tea Set

Q: I recently inherited my grandmother’s silver tea set and am interested in the history and value of it. It includes a footed teapot with a wooden handle and knob on the lid, footed sugar bowl, footed creamer and tray. (The fourth piece in this picture was returned to the estate.) The tray is marked “Barker Ellis” on the bottom. The other pieces have four hallmarks on them, the initials “JTH over JHM,” an anchor, a lion and the letter “C.” I’m interested in the history and value of this tea set.
