How to determine the age of a Voigtlander Lens

This is information that I have collected over the last few years from a number of sources. Some of those sources contradict each other so I have had to make decisions as to what I wish to keep. I cannot guarantee its accuracy.

The date a lens or shutter is made is not always the date the camera was made.  Both lenses and shutters are made and sold to camera manufacturers in batches.  A camera made in one year may have a lens made the previous year. It is also possible that either the shutter or the lens is a later addition made by a repairer.
