Hey, welcome to the forums. When you say older, just how old. What cams are on the bow? If you can it would be better to post a picture or two and we could be of more help.
9/07 might mean it's a 2008 model, but the more modern FireCat with binary cams didn't hit the market till 2008. Is there a sticker on the bottom limb? If there is and you can read it then the first two digits are the model year.
