Hello everyone, I recently acquired a Crown 4x5, whole but in poor condition, needs some care. I have two questions, how can I remove the bellows from the body? At the back it has 8 tabs that I suppose release a frame that holds the bellows, but at the front I can't find anything similar, is the bellows glued or is the fastening mechanical? My second question, for now... I cannot remove the eyepiece from the top, it has no visible screws, only a tab that is pressed, but no change occurs, and inside the body it has a triangle, It doesn't seem to have screws either, how can I remove the eye viewer? Well, any help would be greatly appreciated. Greetings!

The front bellows frame is held to the front standard by screws that go through the lensboard sliders. The screws go into conical nuts that are behind the frame. Slide the front standard all the way forwards and you should be able to see the nuts.

The tubular viewfinder should slide forwards when the tab is depressed.
