It is get from an old over head projector.
Sorry for the misunderstanding. Actually there is no overlap. In ' fixing the objective lens' section the second image used to make markings to remove the overlapping portion. Focus on the third image, it is the finished one, there is no overlap. Please check the steps. I tried to express it in words. OK. Thank you for your great mind, because you offered a suggestion for me. Thank you.
