A Brief History of the Italian Marque
Blatto & Niri, Corso Re Umberto, 92, Torino (1925)
Built from 1924 to 1931, they were quite fast overhead cam singles. These included a 348cc machine and smaller engines designed by Angelo Blatto. Initially located in Turin, they moved to Bologna in 1926 and the company was renamed FIAB (Fabbrica Italiana Augusta Bologna). The range was extended to include 125cc and 175cc models, including a sidevalve.
When the company closed in 1931, Angelo Blatto formed a new concern, OMB, in Turin.
