I got my waist strap from the website that finallyME gave me, http://www.gunnyssurplus.com/ and found out why my black Alice backpack didn't have any military ID on it although the metal fame and metal buckles were definitively US military. A representative from this website told me that my back pack was almost certainly made in Korea. He said they he had received hundreds of them in time period mentioned (1985) and they were all high quality and made with black nylon and mostly likely made for ROK army.
