Boarhead, I don't know exactly how to date those old bows, but the 7050 is just a model number and I have a Pearson Cougar that says the same thing. I know it was made in the 70's, but no idea what year. it's 62", 45#@28. guys that collect them can usually track down the manufacture date, from old catalogues or directly from the manufacturer. I do know that there is a serial number on the side of the riser below the handle along with the bows' specs. that serial number is the one they use to find out when it was made, I think. you can probably track it down if you really want to.
