Hi Chombi , here is a picture of another frame I found on here with same brazeon .

Reading through the postings attached to that picture it would appear it is shimano specific ? Yes that bushing is a standard bushing that has been (ahem) modified to fit the campag levers .
As to why no shimano levers ? I have not been able to find any that would fit this particular brazeon .
I will have a nosey about through old posts and see what I can dredge up but any help will be gratefully accepted
