The Pearson catalogs kind of petered out after 1977. The bow may have been made for a couple years after 1977 but just was not in the catalogs. The catalogs did not have much in them after 1977. I believe it is a 73-77 and they were good short hunting bows and nice lookers as well. The Rogue was another model that falls into the same time frame. You have a good bow and it should be a good shooting treestand bow for you. Not one to take to the range and shoot 50 targets with unless of course you are more macho than most. Anyhow a good little bow that packs a nice little punch as well.
