Continued from above:


SNCAC, the Société Nationale de Constructions Aéronautiques du Centre, sometimes known as Aérocentre, was a French aircraft manufacturer created by the nationalisation of the Farman Aviation Works and Hanriot firms in 1936.


So SNCAC designations were like this:


NC 2230 (formerly the Farman F.223)
NC 2231 (formerly the Farman F.223.1) long-distance bomber/mail plane prototype used for distance record-breaking
NC 2233 (formerly the Farman F.223.3) night bomber (10 built)
NC 2234 (formerly the Farman F.223.4) trans-Atlantic mail plane (3 built)




I have found no NC designation for the Farman F.234 but there is a reference in "Les Avions Farman" by Jean Liron (out of print). In a list, there is Farman F. 234 with a code of F-ALHF and a date of 1931, with 16 built.
