Leica packaging changed through the years. The box type can sometimes be a means to determine the age of a product. Specially for products without a serial number it can be difficult to determine its age. Apart from the box type I know that the logo's and trademarks of Leica and Leitz have changed over the years. In Leica collector's guide second edition by Dennis Laney you find these changes in logo on page 40. But so far I haven't found a source that tells me the period that the different packaging were used by Leitz.
I know it started wit dark red boxes without any text on it. Then came the dark red boxes with text, later the lighter red boxes, then a greenish box, red and white and two white boxes. The last box type is Black/silver. See photo.
Can anyone tell the period that these different boxes were used.
