about 50 to 120 bucks depending on condition and it looks to be in great shape. i have one early compound in my collection. Collecting vintage compounds hasnt caught on like collecting vintage recurves and longbows. I dont think it ever will honestly so my suggestion to your friend would be to just hold onto it. The money isnt worth getting rid of it and its a cool piece of archery history. there is one early compound out there that is worth some money and thats the allen adventure simply because it was the first compound. Thanks for sharing
