Vintage spalding bat (black betsy look) centerbrand question

[autographedgamers]

Hi,
I cannot seem to find information regarding when this bat was produced. I cannot find another example of a spalding bat with the centerbrand in script. There are no other markings on the bat or knob. The bat is 34.5 inches and 39.5 ounces and looks like a black betsy type. There are remnants of some kind of small circular decal to the right of the center logo. any help or comments is greatly appreciated! Rob
