bought a used martin jaguar on e-bay. bow is complete ready to shoot and in excellent condition and even came with a hard case. my question is how do i know what year it was made (the info on the data tag is worn off) and what kind of cams do i have. i can't post pictures since i'm not registered and the site won't let me register, so it's a catch 22. i can tell you that both the cam and the idler wheel are silver and i found the lettering "F5" on the cam along with "M-Pro" . it is real-tree camo with a black rubber grip and i can make out the peak weight is 70 lbs and the string lenght appears to say 86. any help is greatly appreciated.
