I'm pretty well settled as to what I've got, between the group's assistance and my own research. Thank you very much, I've definitely learned something new.
The Simplex drivetrain, however, is driving me nuts. I've obviously got to learn a lot more about Simplex. Those white shift levers go against every preconception I've had about the brand (but it's not like they're rare, I found a setup on eBay at a very reasonable price within ten minutes of starting to look), and the rear derailleur is just odd.
