The bike I worked on was a World and tagged "Chromoly 4130". It looked like a mid 80s bike. I've seen other Schwinn's from this time period, particularly the Tempo, which is a very nice bike... a little lighter than this "World".
Schwinn wasn't sure of they wanted the Schwinn name on these bikes, so they sold them as "World" bikes te first year. They were a success, so Schwinn slapped the Schwinn name on them. If the World is cromoly, I'd guess the Schwinn World is too.

Those aero levers make a nice upgrade. Stem shifters? Really, I don't see the problem. They'll be just fine for the OP's commuter.
