People are prone to taking Golden Jubilee emblems and installing them on 600's. If you are not familiar with the various models you could have wound up with something like this.
One easy ID is to look at the rear axles. in the center of the wheel, the NAA/Jubilee has a large nut and cotter pin, while the 600 series has a bare axle end. The Jubilee has a hub and axle shaft separate like the 8N and earlier, retained with a nut. The 600 and later uses a one piece axle shaft and hub like on most automobiles and light trucks.
