There has to be a story behind these.

SB single pointed their leadscrews ?

I would have thought they would use a die head with a lead screw feed, or a
thread grinder, or a Cri-Dan, etc.

Inquiring minds would like to know.

They had special machines that cut the leadscrews, single point, tool front and rear, cut in both directions, automatically and very accurately.
