I believe the glass color is correct on that bow for that year.With the larger standing bear decal the bow is a 1954,the blonde colored glass was last found on the 1952 Grizzly I believe.'53 has the same orangeish/red glass as this one with the small running bear decal.As Bjorn said,I believe the initials were placed on the bow at some time by the owner,I doubt the it was done at the factory.
