Love your cockpit, Frog. As Jags says, a class act.
About a mirror, it's a very tricky thing to mount on a Rohloff-hubbed bike. There are three strategies that I've used successfully. The first is not to mount the mirror on the bike at all but on your helmet. Bell makes helmets that take mirrors. I have had the Bell Metro and currently have the Bell Citi, both now out of production but still available in some shops; just be sure you can get the right mirror for them, and buy a set of spare pads as well, though my pads still look like new after several years. (Maybe I'm just very clean, or so fit I don't sweat. I wish!) Second strategy is to get a truck mirror on a long arm. My LBS used to sell one that had a crude loop of metal suitable for mounting it to a bicycle handlebar. Crude but actually very efficient. You mount it inside your Rohloff rotary control, brake lever and in my case the heart rate monitor control whose buttons I need to reach with removing my hand completely from the handlebar. The long arm and the shape of the mirror then permits it to see past your upper arm. It works. I had several of those over the years. I saw them advertised on fleabay the other day, so they're still made. The third strategy is to use a plug=-in mirror on the end of your handlebar. Zefal's Dooback is a superior, but fragile and vulnerable (a footbride that I enter at about 30kph with an inch to spare on either side has claimed four of mine as the entrance price for misjudgement) and expensive to replace. The reason I mention it all the same is that if you're a careful sort of rider, it is the best plug-in mirror out there, bar none. I now use a roadie's mirror made by Cateye that costs under a fiver. It is round and, unlike the Dooback which is shaped to give the heel of your hand plenty of space, you can't use it pointed up from the plug at the end of the handlebar, you use it pointing down. It works a treat, isn't vulnerable because it just folds back under the handlebar when it gets banged, and is anyway cheap to replace. The model number is Cateye 300G and I get mine from Wiggle

Still a bargain, and highly recommended for the money as a working solution to the problem of a crowded handlebar. There is a fourth strategy but I haven't tried it, as I wear different sorts of spectacles on different days, and not all of them will focus down at the tab of the front wheel: the fourth strategy is a mirror attached to the fork roundabout the hub
If you're going the U-lock route, and I suppose you'd better set an example to the younger folk riding behind you, the European equivalent of the look Dan was talking about is the Abus Granit 54X U lock. The likelihood is that you need the 30cm length. (There's also a 230mm but the idea is to get the rim, tyre, at least one tube of the bike, and a fixed post or small tree or cast rail or something inside the U of the lock, and the 230 is just too small.) The thing weighs over three pounds but it comes with the best clip in the business, a quick release, quick return springloaded clip I carry on the seat tube just under the side so I can grab it to defend myself against carelessly driven Range Rovers in the narrow ways I ride in. There's a choice of clips but only one comes in the box, and all the others are less convenient in use, so buy the kit with the right clip in the box. Also, buy a hefty chain; Abus makes several that match the lock) and are locked up/unlocked with it.
The n'lock is convenient and is all I use, but I live in a low-crime area. In the sort of situation where even a broken bike, which is what the n'locked bike appears to be, may be stolen by someone with a truck, or where the bike may be stripped of components, one needs the 54X anyway, and the hefty chain that accompanies it, rather than the relatively lightweight cables that work with the n'lock. (That's given me an idea. Gazelle gave me a hefty chain in a canvas sheath to plug into the ring locks on my Gazelle Toulouse and Trek Smover; I think I'll see if the pin on it doesn't work with the n-lock; that would be terrifically convenient.)
That red on your bike is really very racey!
