This is the SBE Cortez, a deluxe AM mobile rig.  It featured 23 channels, Volume, Squelch, a switchable noise limiter, and a PA.  I first obtained one new in the box in 1976, after another CB'er traded me for a 2 tube, 75 watt amplifier which I had built.  This model had great transmit audio, and a fairly robust receiver.  One of the most annoying "features" of this radio, was the manner in which the Channel "22A" was defeated in the blank spot. While some radios had one jumper, or one or two spots missing on the selector switch, this radio had a total of 4 defeats! There was no way you were going to wiggle in the channel on this radio, no matter how careful you were.  Part of this might be explained by a curious PC board stuffing option, which included a crystal, and associated components and was marked on the schematic as the "11A Option".  Evidently, in some markets (Outside the U.S., I'd presume), this radio could be equipped to operate on 27.095 in the blank detent by installing this option.

I used the Cortez as an alternate radio on the base, until I got my car in August of 1976. After that, it saw regular duty as my mobile rig until I traded it for a Tram XL5.  I picked up another Cortez around 1979, and used it for a few years until I was forced to "clean out" my excess stuff. There were a few others in my area who also ran a Cortez, including Blue Bandit, Cougar, and Money Man.
