I happen to know Sean.  He's based out of the San Diego region (the History Channel flies him in for the show and puts him up on in a hotel for a week while they line up a bunch of "visits").  He has a ridiculous collection of European arms and armor (the finest privately-owned pieces I've ever seen are his, and they have a price tag to match!), and does a brisk business.  He supplied Disney with the edged weps for the Pirates of the Caribbean franchise (which were all real, BTW)...  But IMO, he undervalues ethnographic weapons.
