Societe Anonyme Pour La Realisation D’avions Prototypes / S.R.A.P.
Established at Billancourt in 1926 to build aircraft to the design of Louis Becherau, formerly with Deperdussin and SPAD. First production design was the C.2, a two-seat monoplane powered by a 500hp Salmson engine.
The Paris-based S.R.A.P. is often listed as the ‘Société pour la Réalisation d’Appareils’. Flight truncated the name as ‘Société pour la Réalisation d’Avions’. However, ‘Prototypes’ seems important as it suggests that S.R.A.P. did not intend to manufacture aircraft designs in series.
