Sal, and all... The story of the Van Ordens is a real tale of one of our great families!! A couple of years ago the NRA did a nice write up on them. Reference to Evaluators Ltd is in the story here:
Shooting Sports USA | Gunpowder In Their Blood: Four Generations Of George Van Orden
This story originally was published in "Leatherneck" magazine.
Sal.... Speaking of "Leatherneck" magazine, here is an advertisement for Evaluators from a 1952 issue of that magazine:
As you can see, the business was alive and well in Quantico back then, under the direction of General Van Orden!!
