Indeed the British government poured tons of weaponry in Portugal, to establish a 'joint venture' for the defence against Napoleonic troops, but this would not be the case; 'Manuel' may either be Portuguese or Spanish, but the name 'Deja' or started by 'Deja...' can not be Portuguese; so its Spanish by exclusion.

Not rejecting the colonial probability, it does in fact seems as the handle resembles North African work.
