Thinking: what about a ship used by jw missionaries, and vessels are required to fly the flag of the nation of their registry.
would the blue JWORG do? the new earthly symbol of the 1914 kingdom? or are the local colours de rigueur ? for an imaginary HMS "'Lookbryn" ?
seriously though, in the 1930 the government ordered all to fly the swastika, but since no ceremony is involved, could/should a ZJ have done so, or
a local jw done so in Malawi?
