Nelson's was a factory in Aintree, Liverpool. It most recently made Jams and Preserves but obviously at one time made toffee.
It is likely that this Traflagar toffee tin ws produced in 1905 to mark the 100th anniversary of the Battle of Trafalgar.
The condition is very good. I believe this is a rare tin.
