In 1957, I encountered this premium product for the first time. Over time, the original heavy and preferred version has become less popular. It is associated with the Renold 380 and 580, as well as the Daiwa 640 masterless o-ring used in motorcycle practice during the 60s and 70s. This assembly is specifically designed for V-8 models in my collection. To operate it, you'll need to use the provided crank and key, while the camshaft fits perfectly into the dowel hole of the sprocket.
