The Super says 'SUPER' in nice red letters around the front element. There are some optical differences between the Super and the previous chrome (Seikosha shutter) and black (Seiko shutter) 180mm, including coating changes. The original 180mm is not a bad lens - but the Super would have an edge head-to-head. If the shutter is behaving, just put a lens hood on it and make pictures. if you want the details differences.
