This is my favourite commuter earlier tonight: a 1984 Trek 520 tourer I bought on eBay in 2005. I eventually replaced the rear wheel that had the notorious helicomatic hub and I now have mismatched valve stems - not very OCP of me. I recently replaced the original seatpost with a Velo Orange set-back one to compensate for the slightly higher position of a Brooks B17 saddle that I haven't installed yet.

The fenders and pannier are from the Canadian bike company Norco. The pannier generally works fine and holds a fair amount of stuff, but it has a tiny "landing strip" velcro tab so it pops open if it is bit overfilled. I have to special order 27 X 1 1/8" tires (the original recommended size for touring) to fit inside those fenders or else I'd have to go skinnier which I don't want for commuting. That's the West Toronto Railpath below - I went a bit out of my way to get a photo of it for another thread.
