Interesting story....I wonder if she still exists and what actually happened to the 1" on ole number 8s Plaque?
The ciclip style finished with the 2a. Although many have been changed to the later style due to cap wear.
The latch top carby was introduced on the Model 4 Auto. Obviously Twin port for the predicta system. The second port was closed with an alloy plug, when returned for warranty and the removal of the predicta system was carried out.
Due to the Autos demise the twin port cap wasnt necessary. So one port was not drilled and kept permantly closed until CC could retool for the single port top.
The model 4 std and model 3 were fitted with these twin port tops until the single port was released around or just before the model 5 series 1. Twin port tops could be seen on those models in between, around 20,000-30,000 mowers.
