[quote=obsessed-with-doubles]So how did they make the Weldless bbls? I don't get it.

Basically just like making a modern bbl. A solid bar was bored & turned/shaped to size. Difference was the bar was heated & twisted prior to the finishing, thus causing the "Grain" of the metal to take a spiral direction.
