RE: Pearson Colt
As I remember, an x before the weight signifies 1 pound less than marked (two xx' s, 2 pounds, etc.) and an x after the weight signifies 1 pound over. I' ve never seen or heard of fiberglass " webbing" , so it is probably in the finish, but be sure to have someone knowledgeable check it out just in case.
I like the old Pearson bows, and the Colt is no exception. Mostly overlooked by collectors for some reason--maybe because they were mass produced? Still, should be a good bow if it' s not damaged, and plenty for whitetail.
