1) There appears to be some confusion about dates. One source says founded 1951, another 1956. It is entirely possible that there are two different marques, but sales literature shows, so far, only the one. The literature names them as both Società Italiana Moto Scooters and Società Italiana Motoscooter. One source says they closed in 1955.
2) It is believed that Rene Guiller marketed SIM scooters under licence in France in 1955 and possibly later.
