I assume they entered the trade via surplus animals from the SSP?
Okay so, this is probably going to sound pretty conspiracy theory-is, but I'm convinced that I
may have figured out the answer to this question.
In 2009, a man by the name of William (Bill) Gruenerwald died. This is his obituary:
William Gruenerwald Obituary (2009) - Colorado Springs, CO - The Gazette
In 1980, he bought a ranch in far northeastern New Mexico. He proceeded to turn said ranch into a large scale breeding facility for endangered equines. It was called the Canyon Colorado Equid Sanctuary.
You can find a brochure for the real estate listing for the ranch, here:

Canyon Colorado Equid Sanctuary received its first Przewalski's horses in 1989, as this document shows:

Now, by 2007, the initial herd of Przewalski's horses had grown to number
82 animals. As this (Desreputable source) shows:

As detailed elsewhere on this very website by users @
@okapikpr @Tennessee @Safari Park and
@Kifaru Bwana this collection was liquidated prior to William Gruenerwald's death, mostly in 2008. Apparently the rare equids were sold to various dealers via a public auction???
Anyway, about a year ago, I stumbled across an ad for a most unusual horse... A Norwegian Fjord/Przewalski's horse cross colt that is! Here's an archived version of the ad:
Exotic Horse Cross
"His father is a full blooded Norwegian fjord and his mother is a Przewalski’s horse that came from a conservation place in New Mexico." -From the ad.
Now, what "conservation place in New Mexico" do we know of? Canyon Colorado Equid Sanctuary! It's perfectly possible that the colts mother really
did originate from there! Equines are long lived on a whole, plus Przewalski's originally from CCES still exist within the AZA's Przewalski population!
Yes, really! One of the two P-Horse mares that relatively recently arrived at the San Francisco Zoo is stated to be from there! Source:
FYI: The San Francisco Zoo Just Welcomed Two Rare AF Horses
So, I propose that all privately owned Przewalski's horses in the US either originated from, or are the descendants of animals originally from, CCES. The timeline just fits
too perfectly for that to
not be the case.
Plus, I know of no other source/s of P-Horses that private citizens could've gotten their hands on
other than the CCES dispersal.
Oh, and just for fun: Abe Millar's (The "breeder" of the Norwegian Fjord/Przewalski's crossbred colt) website:

As the
many photos show, he
definitely has a breeding herd of P-Horses.
