Did mine in 1992, it was called the Advance Deer Stalkers Certificate back then. Richard Prior and Andrew De Nahlik were instructors. The shooting test was done with the newly introduced Brown Bess musket.
Even back then it was totally geared to learning 'how to manage people and the landscape to cope with deer'. Very little to do with actually stalking (it was assumed you knew how to do that). I've used the Hoffmans Pyramid a few times since - mostly to hide behind and confuse land owners
