I play with two old Helmstetters I purchased new back in the 80's in NYC.
One is a 87-14 and the other is a 87-4. The eight point 14 is for straight pool only. The 4 is for everything else including break stick. Both roll straight and true.
I have a couple friends who play with older Helmstetters. I don't think either of them read AZB. Both cues are very nice and have great old-school sounding hits.
