It was needed a number of Mission to wear a crusher type?

Thank you for your help. I base my research on the ASMIC MP catalogue.

The sales cards are great documentation to prove the manufacturer was Dondero, not Dennison.  

THANK YOU MUCH ! I'll give it a shot & see what happens ?        Best,   Dom

Once he got his crusher he most likely put away the visor that started this thread hence the great condition.   Very nice that it’s identified.

I found and and purchased both of  those aviation-related bars in early 1984 at the Camp Red Cloud, Korea Army Clothing Sales Store. They are both the in N.S. Meyer packaging 

Thanks for your instructive posting and yes I suppose our man could have the crusher hat that wear on that pic  and the no crusher one that Im going to manage.

In your original question you ask if there is a difference between US Army and AAF officers caps.  The answer is no, there is no difference.  AAF is Army Air Force, so no difference.  However many associate the Crusher or Crushed caps with the AAF.  Towles apparently also had a Crusher/Crushed cap as the photo of Towles posted by R Leonard shows. Not all that uncommon for an AAF officer to have more than one cap.  One for dress uniform and one for flight duty.  Hope this helps.

As far as I can see, my patch is about as identical as a hand made patch can be, to the Italian made beret example shown here:  http://www.insigne.org/509-I2.htm      

Also have you black lighted it yet? That would definetly help
