Not very many.
I lived in Springfield, MO, and this is what Andy did for marking his early cues were pretty popular locally. I would suggest finding these cue would be more local to the Southwest Missouri region verses the broad base as his cues reach now.
Like most cuemakers, these earlier cues are a little simpler and frankly you will see less perfection than you see in his cues today.
Darrin Everett had one of his earliest cues and it perhaps one of the best examples. That would be a true treasure to get that cue.
