Hi my name is Dawn and I am new here. I have a set of four wall ducks stamped on the back, "Genuine Staffordshire hand painted Shorter & Son England". They came from my late grandmother but I am not sure just how old they are. I have spent many hours trying to find out more but to no avail. I can find many Beswick ducks but not Staffordshire. Each duck is numbered one to four. Can someone please give me an idea as to their age and value. The ducks all fly to the right. I would be most appreciative.
