Aerfer[1] was an Italian manufacturing company created in 1955 by the merger of IMAM and Officine Ferroviarie Meridionali. The name is a contraction of Costruzioni Aeronautiche e Ferroviarie (Aeronautical and Railway Constructions).
In the 1950s and 1960s, Aerfer manufactured bodies for trolleybuses for several cities, particularly in Italy[2] (including the Naples trolleybus system),[3] but also some for foreign trolleybus systems, such as those of Mexico City and Istanbul, Turkey.[4]
In 1969, the company merged with Salmoiraghi and the aviation division of Fiat to create Aeritalia
