Would be interesting to see the back side. But if it is uses the same chrome plated pot metal base as the GTA emblem, the casting number would be the same, and of no real help.
I looked at all of the 1960-68 text search "hits" for the individual words "sport" and "sprint" and there were no emblems.
Then I looked at the illustrations and noted that basic part number 16098 was used for emblems on the lower fender behind the wheel, and 16228 was used for emblems in front of the wheel. A search of both of those yielded no "sports sprint" emblem of any kind. Therefore it was not serviced, at least not in this comprehensive master parts catalog dated 1968. Nothing in the 1967 single year car parts catalog.
