Larry -
It's also worth noting that the bust tilt on yours is different from both of my common color Colavito's AND all of the ones that I can see on eBay right now. They all seem to have this same bust tilt:

The front of the neck lines up differently on the "N" in "INDIANS" on yours. Maybe your bust tilt can be found on others? I don't know.
