That's an 1987 traveler. 4130 double-butted steel. 26 lbs spec weight. The Exage bits and the steps are not original to the bike (as is the saddle), and there were probably later upgrades. Clean it up and ride it. These are great all purpose bikes. If you want to know the original spec's look at this:
