Some .22 cal boxes


#1

One man presented me some RWS .22 cal. boxes of different periods. Here the picture with them.

Is it possible to identify the year when those boxes/cartridges was made?
On sides of the boxes there are mentioned the manufacturers:
Boxes # 1-3 - Dinamit Nobel, Troisdorf, Germany
Box #4 - Dinamit Nobel, Fürth, Germany
Box #5 - RUAG Ammotec GmbH, Fürth, Germany

When Dinamit Nobel moved from Troisdorf to Fürth? Did manufacturing facilities also was shifted to Fürth?
