1980 is what i decide from catalogs as well (found them online.) I picked it up this afternoon. I think even the tires are original. I took the wheels out and I dont think they have ever been out of the frame before. Its amazing that a bike from 1980 could have hung around this long and no one ever took it our for a spin. S/N is Z920319 if anyone can date it from that.
Thanks for the replies.
