Really? W. J. Jeffery & Company were not gunmakers? I thought William Jackman Jeffery was a London gunmaker and was responsible for the development of the .600 NE? I'm sure we're talking about two different "Jeffery's".

I would also add the name Rigby as an inseparable to the aforementioned names above.

Choosing the top three is tough!! Also, at what point does Boss drop off the list?

Obviously, I could never choose only three
