Thanks for that but the hallmarks are certainly TB but are way too small to take photo's of similar to a hallmark inside a ring I do the believe the knife was purchased from a jewelers

I have found an auction in 2004 at Christies that has the same makers mark as you describe but year mark is 1991.

The only suggestion I can offer is to contact the Edinburgh Assay Office and see if they can shed some light on the mark. Cheers and good hunting.

Thanks Downunder kilt for your time and effort those stags at christies are rather nice aswell. You would think there would be more on the silver smith with this level of work.

In addition to Mikes great efforts in trying to track down the maker, I have discovered three more registered silversmiths from 1770 to 1805, without seeing a closer view of the hallmarks it's difficult to say if any of these makers are the right ones, but it may be interesting to follow them up.

Here is a link to the web page which includes the three TB marks -
