An Eclectic Mix
Our acquisition interests are not just limited to rare cipher machines and books on cryptology. In the recent past we have acquired many artifacts of unusual interest. They include a rare WW I Army Signal Corps poster; a rare Jedburg Silk used by Special Operations Element units to communicate with London HQ during WW II; 80 photographs of a WW II era Code Room in Washington D.C.; four first day stamp covers issued by the UK to memorialize Bletchley Park; two rare bronze and copper Chinese cipher locks that use combinations of Chinese words to open the devices; and a U.S. first day cover stamp of the German Enigma machine issued to commemorate the work of U.S. and allied cryptologists during WW II.
Some of the unusual items acquired since 2007 are depicted below.
