I really don’t see how a wildcat can post-date a factory cartridge.
I suppose this is another of those mysteries that we will never find the answer to since most, if not all, of the initial players are gone.
If I had to guess, I would say that Dr. Somovia did indeed design the original cartridge as a wildcat and then convinced (or paid) Norma to manufacture both brass and loaded cartridges to his specs. (Don’t forget, the 7x61 S&H started life as a wildcat and was later picked up by Norma. The 7x61 S&H is different in that rifles chambered for it were made and sold on a commercial basis. Any rifles chambered for the Condor would be custom re-barrel jobs.)
There are other examples of the same thing happening during the last Century and today, with so many case manufacturers in business, it happens quite often.
All of this, in turn, raises the age old question of, “is it still a wildcat?” Does the simple act of having brass made with your own headstamp turn a wildcat into a non-wildcat? If the 258 Condor is no longer a wildcat what about the Rocky Gibbs cartridges and more and more of the Ackley designs that we see today in new brass with a proper headstamp?
It used to be hard enough to define a “wildcat” but I pity the poor soul who decides to make that his collecting specialty today.
