Just stumbled across this about a union jack that was at the battle of trafalgar,that  sold for  £384000 back in october 2009.
Amazing and this town made the cannons that were at trafalgar

shh but I have borrowed the image of the flag,which even as musket and shrapnel holes and smells of gunpowder.
