Way back in the late 70's this was a knockoff of the original Gold Hound pans. Never did much business but market just wasn't there as even the righteous gold hound was sold so the inventor could go back into coal/oil mining. I would have to go back through old ICMJ/GPAA issues to ID but definately long gone. The chemical bond has let go and it will crumble into nothingness pretty quick with use. You can save with automotive bondo to seal,sand and reconfigure. These units had very little/any UV protection as you can see. Lotsa luck with your antique. John
