South West Africa
Postal History / Customs Duty 1929 (23rd October), incoming cover from England franked with two KGV ½d (SG 418) tied by a London (23 Oct) machine cancellation. The envelope was unsealed and the contents deemed liable to customs duty (the printed company details at upper left presumably suggested the contents contained advertising material). A bilingual ‘CUSTOMS DUTY / INVOERREGTE / ½d’ boxed cachet was struck in black and the ‘½d' altered to ‘1d’ in manuscript. The duty was receipted by the affixing of a lower marginal South Africa postage due 1d black and carmine overprinted ‘S.W.A.’ (SG D43) and tied by a KEETMANSHOOP (16 Nov) double circle datestamp. Although Customs Duty stamps were available from some South African Missions abroad whereby firms sending advertising material to South Africa could prepay the duty, South West Africa did not have specific customs duty stamps and it is not clear if those of South Africa were valid in the territory. Envelope with central vertical fold. Very scarce.
