This is a 1963 Big Valve Super Rocket which was recently imported into Australia from the U.S. It had Illinois registration, the plate is still on it.
Note the 140 MPH speedo and the window type ammeter. Also has filler plugs in the fork top nuts.
The headlight switch is the early type but I thought that the 41SA switch should be fitted, but I could be wrong.
It has the late barrel with the fancy front fins.
All up, pretty original.
