I have followed the thread with great interest. Saying that I know little about dadders, but have always thought how beautiful these pieces are and would love to own one. Having said this, my spear is the struck art, medals and the like. Fine silver is also a collectable for me. What I do find concerning is the silver marks and maker marks shown. I would offer these are cast in the piece. This is something I would find HIGHLY SUSPECT in a piece of silver. Three examples, leaves me with very bad vibrations.
