Page 4 - details of the Gretsch Viking, or models 6187, 6188 and 6189.
The Gretsch Viking was available in three finishes, each with a unique model number. Sunburst (Gretsch 6187), Natural (Gretsch 6188) and Cadillac Green (Gretsch 6189). The most expensive of these models was the natural finished Viking ($700), followed by the two colored finishes at $675.
The Viking says "winner" any way you look at it. From it's shaded golden sunburst hollow body to its advanced features found only before in a custom guitar.
The Gretsch Viking debuted in 1964: early Viking examples had the Viking longboat motif on the gold scratchplate, but by 1968 this was gone, with, as pictured below, solely the word Viking above the Gretsch logo.
