Looking good!
Would love to see at least one guy, carrying large, heavy dufflebags, with the tip of a rifle slightly protruding, just for grins. Mad Mike Hoare and 'is mates shouldn't 'ave all de fun on de African continent.
I forget which small country they were planning to take over, when someone spotted the weapon, but a major kerfluffle in "customs", and/or at the airport ensued after someone spotted that little error.
As for the machetes, shouldn't be too hard to scratch-build those, with a little ingenuity, and some styrene rod and plasticard.
