Can you display any of the pics? I could tell you possibly what model/ values.
Parts , or anyone to work on them is hard to find, but YOU could do it yourself. I have two and my wife and son each have one as well. I do all adjustments and work myself. They are a lever action recurve ( only one string). Their most popular bow were the "Aeroforce-x80". New models are still produced, and are very expensive.
I belong to this site "American Eagle Bows", which you can learn a lot about the older generations and many sub forums where you can get the manuals online,as well as classifieds.
