1916 (Jan.) Admiralty cover to England, headed "On Active Service" with Belgian Congo 25c tied by single ring c.d.s (Kabalo?) with fine violet boxed "PASSED BY CENSOR / No. 25", initialled "H.M.H" by Surgeon Captain H.M Henschell. Very minor edge stains, otherwise fine and rare, just three other examples of this censor cachet recorded by Pennycuick. Photo on Page 188. (Image1)

1916 (Aug 31) Long stampless O.H.M.S cover to the Paymaster of H.M.S "President" in England, with blue Albertville c.d.s and blue crowned oval "ON NAVAL SERVICE / OFFICIAL FREE / ASSISTANT PAYMASTER, AFRICA EXPEDITION", vertical fold, otherwise fine. Very scarce, one of four examples of this cachet recorded by Pennycuick. Photo on Page 190. (Image1)

1917 (Oct 24) Registered cover to London headed "On Active Service" bearing Rhodesia Double Head 1/2d + Admiral 1d and 21/2d cancelled by two strikes of "ARMY POST OFFICE / 2 / NORTHERN RHODESIA" c.d.s with light "PASSED BY CENSOR / NO 26" with central "anchor" initialled "adms" in ink, blue crayon "R228 KASANGA E.A", backstamped at Broken Hill (Nov 16), Abercorn (Oct 25) and London, flap missing, otherwise fine and rare. A virtually identical cover with registration number 227 is known sent by the same person to the same family on this very day; these two covers are the only known registered items with an A.P.O Northern Rhodesia c.d.s, the number 2 c.d.s being rare in its own right (with just six other examples recorded by Pennycuick). A superb cover. Photo on Inside Back Cover (Image1)
