Age, condition, name on bow, lams used, palm swell, wood combinations, use of carbon, length of bow, grip material, weight of pull, one piece or takedown, and right or left hand are all used to determine the value of your Massie "Longhorn". Of course the most important factor is how much the buyer is willing to pay. I'm right handed so your bow would not interest me, but Mark, the bayoulongbowman above shoots from the wrong side of the bow, so he might be just the man to take it off your hands, if it is for sale.
