This is a Motorola "Suitcase" set. This set uses the same internal parts as the VT-71 but is housed in a luggage type case. Like the VT-71 these sets are fairly common although it is somewhat difficult to find one that still has the antenna parts and a good case.

This set was covered with mildew spots when I got it, fortunantly they all cleaned off nicely! The set is about as clean aand complete as you could ever hope to find.
