Cruisin' on my Bluebird
AMF used that chain guard on the 1959 Flying Falcon (I've been told it was originally a Shelby guard), and that's also about when the star sprocket came out, but I think 1957 was the last year for the serial number on the bottom bracket. Maybe stamped late in '57 for sale in '58? Except I don't see a "G" beside the serial number, which a '57 should have if my theory is right.Maybe 1958/59....???
