I searched the name on the tank online and came up empty. My best guess is it's Chinese. Some of the Chinese companies change names but still make the same thing. It may not be made anymore. Someone in the Chinese section may be able to help.
I tried to look it up too but couldn't find anything either. The serial number brought up nothing as well. Does it at least say anywhere what the displacement is? I can't really tell how big it is in the pic.
