Is the Barry Halper Collection Authentic?

Yes, you read the headline correctly.  To understand what I am talking about go here and read the article.  Ok, lets think about this for a second. 

At one time the Halper collection was considered the most extensive and greatest collection of them all.  People drooled over having some of this cool, older stuff.  But now the authenticity of some of the items are coming into question.  I don't know what to think about all of this.  Back when these items were first donated there was little in the way of being able to ascertain the authenticity of uniforms, but now as more people are researching there are questions being raised.  I would guess the lesson to be learned is that we should be careful when buying something expensive, making sure we do everything possible to determine authenticity before buying.
