Unidentified hallmark - any ideas?

[aliec1]

We've searched this site to no avail and would love any insight! We came across this salt shaker on our property soon after we moved. We cannot find any information about the hallmark. The shaker itself is about the size of a chess board pawn. Any ideas?
