Unidentified makers mark I.D over T.N

[Peartree]

Hi, can anyone tell me who the maker is of this large 1818, London silver gilt snuff box. The maker is I.D over T.N in a square cartouche. Thank you

This is the mark of James Davies & Thomas Northwood who registered this mark 10 Sep 1818 as goldworkers.

Just noticed that the registration was almost exactly 200 years ago - out by only one day!

Thank you. What a coincidence

I found this in the London Gazette on the disolution of Davies and Northwood partnership. It looks like they were jewellers who lasted just 10 years. I think there is a chance the “medal” fitted to the lid of the box is earlier in date and solid gold.
