Hi Wayne, What you found is a tank made by a company called Metaframe and they have been out of business for quite some time now. The nice thing about that is that it pre dates silicone. The glass can be a easy fix if you are handy. The tank is put together with a product called bituminus tape. It can be picked up at a auto motive glass shop. If your interested you can drop me a email. bmssammon@comcast.net
