I possess Welnner hollow ware and cutlery, on which are the following marks: in the left the Wellner die with the pip combination 1-2-4, followed by the name of Wellner (and not "Wellner & Sons) and followed to the right by the numbers 90 (within a circle) and 3 (within a square).
I am looking for more information about the history and origin of this kind of Wellner hollow ware? Please, can you help me?
