The way I remember it, Columbia 300, Track, AMF and Dyno-Thane were being produced in San Antonio. Lane #1 was also being poured there on a contract basis.
Feel free to correct me on this, but Ebonite was already aligned with Hammer through an earlier purchase, and then bought out Columbia 300 and Track and moved them to Hopkinsville, Ky., leaving the San Antonio plant without an owner.
900 Global then forms from ... somewhere? not sure who ... and took over the plant. They received the rights to make balls under the AMF name in the deal, and retired the Dyno-Thane label outright, although they probably kept the patents/copyrights/etc. They also were still pouring Lane #1 on a contract basis. But the main thrust of the company was to make balls under the AMF and 900 Global nameplates. The original coverstocks had "S" on the 900 Global balls followed by a number, and "F" on the AMF balls.
I believe The Break was 900 Global's very first ball. I can't remember whether AMF got a Nighthawk remake, or whether the Code was the first one, but if the Code wasn't first it was certainly one of the first. Not long afterward, Lane #1 went belly up.
Then, Storm aligns with 900 Global and eventually moves everything to Utah after a period of time making balls in both locations. I was told by a Storm staffer last month that Storm technically owns the AMF license now, too, but nothing is being made with that label. I have no idea what the fate of the San Antonio plant was.
