They actually belong to my fishing partner. He got rid of his boat years ago and had them lying around. When I got back into fishing he told me to keep them on by boat and use them. They are old but in very good shape. They do collapse / fold up and make them easier to store. Not sure even if you can still buy them. But there has to be more around. Try to Google them. Sorry that's all the info that I have. I'll try digging them and see if there is more info on them.
