The year was 1973 and Clint Eastwood’s “Magnum Force” is the #1 box office hit all over America. Probably the best supporting actor award should have gone to the Moto Guzzi Eldorados that all the rogue cops rode. It was great advertising for the new Eldorado line from Guzzi.
Except they weren't Eldorados! There's one shot that must have had the camera located where the right saddlebag was. It plainly showed the battery cover with "V750 Ambassador" on it.
The last photo isn't from "Magnum Force" but from "Harold and Maude" with Tom Skerritt as the police officer.
The saddlebags on the Eldorado for sale were made by Wixom (or possibly Arthur Fulmer that apparently bought the molds from Wixom).
