No CHRP Mac ever shipped. The closest anyone ever came was Motorola with the StarMax 6000. The CHRP spec evolved into the New World ROM architecture used from the original iMac to the end of the PowerPC era, though.
There was indeed a PPC version of NT that was designed for CHRP. But, separate from that, Apple also seriously considered using a custom version of NT with a Mac-like GUI to replace the Mac OS. It was one of many options under consideration along with Be, NeXT, and Solaris.
Sorry my post does look to reflect that they did, but yes the full CHRP never shipped, but the portions that allowed NT to run on the PPC did. There was a working version of NT that ran on Apples and the clones.
