    The schematic shows no elements behind the aperture (the two vertical stripes). So no rear cell.

    This lens is a bit unusual in its build: the entrire optical group is in front of the shutter/apperture.

    In this way the "rear"cell is in front of it.

    Peter, I service these 180s all the time n can tell you for certain, there is no rear cell. The entire front cell, everythnig in front of the shutter, comes out like a light bulb, completely hermetically sealed.

    In all the years, I have never had any with lens separation. They may be fungus eatten or scratched but never separated. I should crack an old one open to see if they have any glued elements at all. I wonder? They are really built like hand grenades.
    Anyone can make a Digital print, but only a photographer can make a photograph.
