1918 (Mar 31) Stampless O.A.S cover to the stamp dealer W.T Wilson in England with "FIELD POST OFFICE / 8" c.d.s applied at Mbamba Bay and violet boxed "POSTAGE FREE / PASSED BY CENSOR" (with "BASE 4 N. RHODESIA" excised from the central line - see previous lot), the cachet signed "J. Brown Lt." Pennycuick records six covers with this cachet, all sent by Pte L.H Rivers from F.P.O 1 or 8 in March - May 1918 and signed by Lt. Brown as the Censoring Officer; the continued use of this mutilated Northern Rhodesia Base cachet would therefore appear to be solely due to Brown and Rivers. An unusual item. Photo on Page 188.
