On the (a) rather old and (b) creeping subject of Nelson's Blood, I reckon they put him in a cask of brandy & his blood stained it to look like rum. The Marines guarding him wouldn't have tasted brandy perhaps? Certainly it's rum that's known as 'Nelson's Blood'.

The 'multiple egg cup' shot garlands are also to be seen in HMS Victory, only a couple of cables from the Warrior in Portsmouth.
