Love the image with merv unkie! Note the pullstart carry over and its running the plastic throttle control as well, this id have to agree would be on of the earliest since they abandoned the throttle at this time and also the starter. The starter wasnt reintroduced again until much later in the model 5 run. Model 5 Series 2 I believe. More fantastic info unkie, this thread is fast becoming the premium place for concise info on these models. Thanks to yourself and fellow members. I hope I too can contribute more in the future.
