Peter you are very kind replying to me as quickly as you do, I realise its voluntary so thank you.
After reading a little more I think you are right about it being Hanau silver, although you write "Hanau style". Do you mean it is unlikely to be made by a Hanau silversmith, or do you write that because it can't be confirmed yet?
I also took it to a bullion dealer this morning, they tested it for me and confirmed it is 930/1000 silver. Not sure if this makes a difference to where it was made or by whom but I thought it worth checking as I was originally told it was Dutch! and it could of been made from tin!
Anyway thanks again Peter. I'll be sure to let you know if I find anything further.
The search continues....
