Johns picture shows the effect of a split image but is a lot clearer than the image viewed through this one. As can be seen the semi silvered mirror has a yellow tint and that appears in one half of the split image.
With the cover removed it turns out to be very basic.

Hi Don,
Thanks for the inside view. They are, as you say, very basic. They are also very flimsy and suceptible to damage by knocks. I am sure you realise that my illustration was not taken through an actual range finder. The view through a real one can be difficult to see properly, that is, until you get used to it, as I am sure you already know. How lucky we are today to have auto focusing and micro prisms if you are not a fan of auto.
