Looks like a carrera zeus, not certain when the Zeus became the Volans but from what I've dealt with the Volans was just a new generation of the Zeus. They share similar paint jobs, I remember this yellow, the white with blue like the one further up, and a blue with yellow and blue pattern. I had a Zeus from the last year they made them, I bought it in 2000 or 2001 and the only difference between it and the Volans I bought in 2012, which was a left over from a couple years prior, was the tubing. But the earlier Zeus to the later was the eagle logo, lack of lettering on the BB and slight changes to the style of the lettering. All of them are just really nice frames and worth having.
