Polish Airborne/Para insignia (post WWII)

[DougSA]

Can anyone tell me more about the attached Polish airborne/para badges?

• Round arm badge: I understand that there have been many colour variations of the arm badge and that there were 20+ different colour combinations used by the Air Assault Division during 1967-1986. Can anyone tell me where to find out about the evolution of this badge and the different colour combinations used for the various units?
  
• Breast badge: What does this badge signify and how old is it?
  

Also, can anyone tell me where to find out about the different versions of the instructors 'wings' over time?

I have an interest in the history of the British and Polish airborne forces, as my grandfather served in the British Airborne Forces with the Glider Pilot Regiment during WWII. In fact, assault gliders from my grandfather’s squadron (company) carried men and equipment of the 1st (Polish) Independent Parachute Brigade into battle at Arnhem, in September 1944. He also fought alongside men of the Polish Parachute Brigade during the house-to-house fighting in the Oosterbeek perimeter.

Any light shed on the above questions would be appreciated!
