They would never be legal on the CB band, nor type accepted for sale in
the
ham bands either.

I believe I stated (above) that these radios have never been legal
for use on CB. However, radios for amateur use do not require type
acceptance. Some of the Ranger units listed are marketed as amateur
radios, in amateur publications. Any use other than that is
(obviously) illegal.

Nothing you build requires type acceptance, but if you are going to sell it
commercially, it must qualify.

Notice the ads for new radios where they state that it hasn't been FCC
approved etc etc.
