That's one of the problems with exotic factory wheels that use unique spokes. The manufacturer moves on to the latest "new and improved" version, and forgets to maintain a small stock of spokes for servicing the earlier version. This was a chronic prob;em with Campy wheels (and may still be for all I know).
You might have to settle for a workable analog, ie, right length and head, and reasonably matched gauge, disregarding profile and color.
