That continued through 1938. By 1939, I guess they had used up the inventory of checkered guns and the gun with the plain stock and ringed slide handle became the Model 31A "Standard" Grade.
From the introduction of the Remington Autoloading Shotgun in 1905, the A "Standard" Grades had American walnut stocks and the B "Special" Grades had imported walnut stocks. This announcement appeared in the February 15, 1939, Remington Arms Co., Inc. catalog --
