I love this shot of an old Viner Professional. It’s just such an unusual way to view a bike. I reckon they got a mouse to take the photo. But however they managed it, I suspect it’s been done to show the Viner ‘Star’ cut out in the bottom bracket shell. It also reveals the all important plastic bottom bracket sleeve! Steel bikes need holes at various parts of the frame to let water out and to stop the build-up of moisture inside the tubes. Which is why some frame manufacturers made a feature of these essential holes. But the problem with that, especially around a bottom bracket is water getting into the bearings from the front wheel. Which is why thousands of the cheap plastic, concertina sleeves were sold. Even then water still got into the bearings. Years ago I got into the habit of regularly stripping my Campag bottom brackets and re-greasing. In those days you could even buy new bearings if they were beyond help!
