Wow! Thank you guys for this info..I will stop looking right now!! Actually I am trying to help someone in NZ who had grandparents working in the jewellery trade in Vyse Street around 1910...all she knows is that the factory was divided into 3 sections called "A" "P" & "C" , she has no idea of the name of the firm which is why I posted my question. I don't suppose it is worth her buying a book on the jewellery quarter either other than it will give her an idea as to how these firms looked. Thank you for your help, I do appreciate it very much. Margaret.
