Hi, I have a Fenton Bros EPNS toastrack but cannot find a similar hallmark to roughly age the piece. I have attached an image of the hallmark. It has F.Bros.L:.S and an impressed number 2615. I have seen the Fentone Bros marks at http://www.silvercollection.it/electroplatesilverF.html but none the same as the one on this item.
Any help much appreciated
