Noob here, new to me Nishiki Altron, sticker on main tube says Altron, all green with 1/2 chrome seat stays. Frame labeled "Tang" fork which is white, not green, is labeled 4130. I can't find info anywhere. I will have the bike tomorrow and will post the serial number and pictures.

Is this an Altron? Altron 7000, Altron NFS or something entirely different?

I'm clueless but excited, the bike looks fast and solid. I almost new condition.
