Paul, there cannot be any one answer to your questions that would be both truthful and simple at the same time, because the history of the (one? two?) Neumann company/companies is "simply complicated."

However, one thing is for certain: The company that sponsors this board never made a CMV 563 microphone. It was made by the company that at one time called itself Georg Neumann & Co. (back when there was an East and a West Germany) and now is called Microtech Gefell. Their Web site is www.microtechgefell.de ; they can give you good information and support, but please understand that they are a separate company from the Georg Neumann GmbH on whose site we are here.
