First, The Rolleimeters do not fit all types of Rolleiflex cameras. Then, there are several types of Rolleimeters for distinct series of cameras. You need the right Rolleimeter for a particular camera. I have both a Rolleimeter and the calibrating thing. I would not mind copying the calibration ring and making it available to you. May be a scan turned into a PDF will work. I could look up the camera types Rolleimeters were made for by tomorrow. It is too late for now. Goodnight for now. Ferdi.
