looking for info on bow that I got today at yardsale

Hi I'm from Michigan and I just bought a compound bow at a yard sale today and I need some information on it.
I don't have a pic but I can describe it. allen pat.#3, 486, 495, model Grand Slam, varnished hand grip gold anodized frame brown arms with four rams heads on each arm in between grand and slam. what ever info you can give would be a big help.

 

Thought Hoyt made the grand slam back in the early 90's

 

Thanks for the info, now I know where to start on the restoration.

 

can you post a pic? Sounds like it might be an older allen bow

 

It could be an Allen, it is pretty old but it seems to have been cared for over the years, unfortunately I don't have a pic of it yet.
