?Says "James L. Dalton (1866-1926) acquired exclusive right to manufacture machines under the Hopkins patents"

?But Dalton's first name was Hubert, " (1866--1952) was English by birth and the first born of eleven children." (From Lathes.Uk) Probably a coincidence that Hubert and James had the same birth year though. I know Hubert had many other businesses but office machines don't seem to be part of the array.
