Gibson RB-1 #919-5

The style 1 of the 1930s was a non-Mastertone model and therefore had no true tone ring--only a small-diameter brass hoop on top of the rim.  It did, however, feature the same pot metal one-piece flange and three-ply maple rim as the Mastertones of the same period.  Style 1 had nickel-plated hardware and a dark-finished maple neck and resonator, with white binding on the neck and both edges of the resonator.  Even though the Mastertone models had by this time gone to the double-cut peghead shape, the fiddle-shaped peghead was retained on style 1, with a minor modification--the two small indentations normally found under the fourth- and first-string tuners were absent.  The rosewood fingerboard was inlaid with a fleur-de-lis inlay pattern which is also known by such varying names as "bats" and "flying birds"; in the late 1930s, this inlay pattern was replaced on style 1 by a simple dot pattern, although the "inverted bud" peghead inlay remained. 

Style 1 banjos have an oval "The Gibson" label inside the rim which is similar to the Mastertone label found on the higher models.
