SWBKCB - no.
Transatlantic freight flights on a scheduled basis up until, let us say, 1975, were operated by SABENA, as mentioned, Swissair using DC-4s and then DC-6s, Airwork with DC-4 and later DC-6A and BOAC with DC-7F, CL-44-D-4 and B707.
Lufthansa used a variety of charted DC-4s, including Transport Flug's, between Manchester and Germany later replaced by B727s and B737s but no scheduled 707 freighters were ever flown either to the USA or Germany.
