Subject: [CR]Campagnolo quick release seatpost binder bolts?

When I purchased my 74 Raleigh International, it was fitted with a Campagnolo quick release seatpost binder bolt (curved skewer). I can't locate any information as to whether or not this might have been OEM or even period correct. Come to think of it, I can't think of another bike I have seen with one of these in use. Is this just an undesirable part that people swapped out in favor of a typical fixed binder bolt? If so, why? Or do I have something rare on my hands?
