is that a "Dun Hume" belt ?
Nope, this belt was made under contract for the Air Force. Most likely by Cathay Enterprises or Gould and Goodrich (S&W's contractor) in 1980.
Prior to that, the garrison belt, 2 inches wide was the standard issue. The garrison belt was a joke. Designed for the Class A uniform back in the late 1940's and used until 1980.
There was a concerted effort amongst the Security Police Instructors between 1977 and 1979 to get the gear up to par with civilian counterparts.
I was proud to be part of that group of NCO's that brought the changes about.
Shown below is the makers stamping for the AF.

And the aforementioned garrison belt. Which was really a horrible way to carry your weapon and gear for a shift.

Hope this was helpful. I have numerous examples of all the gear we used over my career. Some of it new and unissued. I guess I'm just an old pack rat.
