Subject: [CR]Campagnolo headset question

Looking at campy cataloge 17 the super record headset top locknut is different to the later version, as it looks like a nouvo record but obviously in alloy rather than the deeper post 1978 nut. I have one on a headset that looks the part but is there a way to tell? and were there later campy headsets that used a similar top locknut in alloy? the one I have is marked "patent campagnolo" on top and underneath but also has the thread size underneath. Thanks in advance
