My printed material on the Peninsular War is not so vast and my Artillery knowledge is even poorer.
However i can't resist to ask: why is this cannon claimed to be Portuguese by (at least) the seller ? because of the motto ? I don't think it stands for such presumption, for such wording is in fact a cocktail. VALOR is both spanish (castillian) and portuguese; Y is (only) spanish; and Lealdade is portuguese.
Maybe who has put up the motto in this cannon was giving wings to his imagination ... and wasn't certainly a Spaniard or a Portuguese
