29 Nov 1949: Rockex Request

After the initial transfer of HYDRA to the Canadian government, documents in the original archival volume from the rest of the late 1940s are scarce. However, there is this request for six Rockex machines, sent from Captain J.N. Wegner (U.S. Navy) through E.N. Drake (The Director of the CBNRC), indicating, perhaps that some of Captain Wilson’s suggestions for the shape of signals intelligence in North America had been taken on board.
