    Greg,

    Now I understand that your Bris (which apparently has 2 glasses)
    must be different from the standard (original) one which has 3 glasses,
    including the shade. Reflection from the back surface of the shade
    must be also
    counted, of course. Still I don't understand how 3 bright and 5 dim
    images were formed (years ago) in my Bris. According to my count
    it should be 3+8.
    
    What do you mean by "groups 2,3,3"? You group by brightness,
    or by angluar separation?
    
    I tried to wipe the inner surfaces with a piece of cloth, using a needle.
    but even the fine needle does not penetrate the part of the gap
    near the acute angle.
    
    Alex.
