So I bought this pricking iron from a lady who says that is has been in her grandfathers shed for the last 20 years. Apparently he worked for Tanner Krolle (doesn't exist anymore, Though it has both website and Insta 🤔).
Anyway, who knows how old it is but I'm going to restore it's former glory and relish that I now have a #6 iron that's made in England! 😄
Video to follow...
