The first picture is a standard 3/8 10 screw that Harvey Martin Bert Schrager used in their cues.
The second picture is a modified 3/8 10 screw that various other cue makers used on their cues.
Jerry Franklin of SouthWest cues used a modified 3/8 10 screw in all of his cues. I will try to find a picture of a SouthWest joint ASAP.
Now the story about the guy who bought North Hollywood Billiards. I do not remember his name and even if I did I am not sure I would use it in my story. When the Italian gentleman retired from his trucking business on the East Coast he wanted to live somewhere with better weather that had a place where he could play Three Cushion Billiards.
While sitting with the new owner we started telling each other pool stories. After a while he started to tell me how hard the trucking business is everywhere and especially where he was located on the East Coast. To be more competitive and have an advantage over the competition he started buying airplanes to offer faster deliveries almost anywhere in the U.S.
With the infrastructure in place he turned his talent to acquiring new customers. He started talking about how hard it was to land a major account. While meeting with the owner of a major supplier, when he saw he that had not yet convinced the owner used his company he asked,
"What do I have to do to get your business?".
The owner said, "I like the new Jag".
He replied, "What color?".
