I never encountered them in my time there, but since it is the crossroad of the old spice route as it were, these guns could have come from a number of sources. For example how did Canadianmade Long Branch rifles end up in the country for use by anti-governmental forces?
Or how did S&B headstamped Czechball end up fired against us on patrol? It was very much a collecting ground for all manner of odds and sods.
