<p>I know this question is 8 years old, but here is an answer to it:<br>
The Contaflex II had 2 types of meter, the early ones had a different meter from the later production.<br>
The manual on the Butkus site only shows the later one.<br>
I suspect Tom has the ealry one shown here:<br>

The lid on the exposure meter has 2 holes and it is used to meter in high light situation and the green range is then used in conjunction with the number that the needle points out. In low light the lid is open and the black range is then used.<br>
