I have been given an all wood compound bow from Martin called a Wart Hog Magnum. I do not know much about this bow and the sticker with all the specks is so old the numbers have worn off. The bow is in great shape though with no striation marks on the limbs and all the hardware looks good. I think it just needs a new string to be ready to go. How do I find out the specks on a bow that is not listed?
