The Royal 59 was a later version of shirt pocket music that I believe came out after 1965 because it does not have the CD markings on the dial.  It is a strong 8 transistor performer with a nice metal grill and recessed tuning dial similar the the 50L except the dial is round on the 59.  Still runs on 2 AA batteries and sold for under $20, another bargain at a time when there was stiff competition for business.  These were still made in the USA.  They came in three color combinations:  Charcoal or turquoise with an off white front, or the harder to find white back with a charcoal front.  I believe the only difference between the G and 1G models was the 1G came in a gift set.
