Bear quiver question

[Mississippi bow hunter]

Can anybody explain how the old Bear archery quiver attached to the bow? A picture would be great.  I have a couple super kodiak's  and they have the inserts on the side of the bow. I just use the great northern bolt on and one of the new bear quivers. My wife shoots an old kodiak magnum. I bought her a strap on quiver and she don't like it. Can those old bear quivers still be found and how good did they work?
