WW1 & WW2 German Small Medal Bar

This item is a German miniature medal bar from the World War I and World War II eras, featuring five different awards.
Miniature medals, typically half the size of full-size ones, were commonly worn on formal mess dress uniforms or for black-tie events. 

Medals on the Bar - From left to right, the medals appear to be:

Iron Cross 2nd Class (EKII): The first cross is a 1914 Iron Cross, indicated by the 'W' for Kaiser Wilhelm II in the center, a common award for a single act of bravery in WWI. WWI Honour Cross with Swords (Hindenburg Cross): The second medal is the Honour Cross of the World War 1914/1918, awarded to WWI combatants, identifiable by the dates "1914" and "1918" on either side of the center and the crossed swords. Imperial German long service or commemorative medal: The third, round medal appears to be a general service or commemorative medal, possibly from one of the various German states, often seen in such groups. Prussian 25 Years Long Service Cross: The fourth cross with the crown and the number '25' indicates long service, likely the Prussian Officers' Service Cross for 25 years. War Merit Cross 2nd Class with Swords: The final medal is a WWII German War Merit Cross (KVKII), indicated by the prominent swastika in the center and the crossed swords, awarded for distinguished service not in the face of the enemy. 

The combination of both WWI and WWII medals on one bar suggests the recipient was a veteran who served through both conflicts and continued their service into the Nazi era.
