I must be living on a different planet. I have owned many different style of Campagnolo cranks (NR, SR, Victory, C-Record and a couple of others, as I recall). Not one had a left hand dust cap thread, nor did any have a left hand one key crank puller. All were right hand threaded.

I am not calling anyone wrong, here. However, this is one time I would like to see some proof of what others are saying about the dust cap thread, and its direction, on these Campy cranks.

Anyone have any evidence, please? Again, not trying to be a smart ass. I just can't understand the rational, nor have I ever seen a left handed crank puller. And I have a Campy one also.
