The Motorola X31A/X31N Ranger were introduced in 1961 or 1962, the later X31A-1 (Gray), X31B-1 (Blue), X31E-1 (Black) and X31N-1 (Ginger) arrived in 1962. I have two of the -1 versions which dropped the Ranger name but were upgraded with an external antenna connector.  They are 8-transistor designs featuring a tuned RF stage, three gang air variable tuning condenser and a decent-sized 5 1/4” ferrite rod antenna for potentially excellent performance. They include a unique leather cover which can snap on the front for protection during transit or placed on the back for convenient storage…pretty cool. Originally retailing for $49.95 they may have sometimes sold for as low as $35 or so. Neither worked as received so I had to get them playing before I could evaluate them.
