Moto Guzzi V700, V7 Special, Ambassador, 850 GT, 850 GT California, Eldorado, and 850 California Police models
Earliest models did not come with fender reflectors at all. Once legally required, Moto Guzzi fit the Lucas RER25 fender reflector with a wide chrome rim (amber in front and red in back). Later models (perhaps around 1973, although my Ambassador manufactured in came to me with the later fender reflectors) used the Lucas RER14 fender reflector with the very narrow CAD or Zinc plated rim. Thanks to Charles Hamer, Jahn Olovsson, George Dockray, and Charlie Mullendore of Antietam Classic Cycle for sending me this information or posting this information on the old Yahoo! Loopframe_Guzzi news group (which has now moved to Groups.io).
