F257 appears in an advertisement for Compagnie de Navigation Fraissinet et Cyprien Fabre. Its proper attribution among the Fraissinet company names is unclear, and Rosanoski considers that it may be an incorrect rendering. No funnel is shown with it; the funnel association is assumed.
Brown 1958’s index assigns C865 to the merged company. Merchant Ships 1959 instead shows vessels retaining their original funnels; Merchant Ships 1963 indicates continued separate trading routes, with Fraissinet as the African Lines. The advertisement showing F257 provides further support for continued distinct usage.
Compagnie de Navigation Fraissinet et Cyprien Fabre was formed in 1955 when Paul Fabre ceded his company to Fraissinet, then presided over by his son-in-law. It managed some vessels for the French government. In 1965 it merged into Compagnie Fabre, Société Générale de Transports Maritimes, which was ceded to Chargeurs Reunis.
