Trafalgar related items included an item labelled as the quilt from Nelson's bed on board ship[5] and a "scenic interpretation" of the battle and death of Nelson[3]
But in addition to Trafalgar commemoration, as the name suggests there were naval, shipping and fishery related exhibits.
Naval related exhibits included
Captain Cook's chart rule[6] and his plane table[7][8]
Fishing displays included the opportunity to observe fishers mending nets and divers in a diving tank.
Shipping related exhibits included an eight foot model of the Empress Queen (which also appeared at the
Glasgow and
Franco-British fairs)[9] and a village of
Amerindians in which war canoes were shown. More actively there was the opportunity to take a submarine trip.[3]
