My Peugeot UO8 was converted to IGH around 1974. It has a late-70s S.A. 5 speed on it. One of my more successful bikes; now ridden very seldom.
It does have a Raleigh fork on it so it has no need of a french headset. The original fork broke in the middle of the steering tube as I was on Mt Auburn St. braking for the Aberdeen St. traffic light. Your quiz if you care is to tell me the city and state.
