Magazine Questions

Hi Jerry, This was news to me too, until I read the Sturgess book. The magazines were made from weldable sheet steel that was folded around a die and welded along the spine. The exterior was then milled, ground and polished to the correct profile. Apparently this method of seam welding is being used, to this day, in the manufacture of cheap bicycle frames. Best regards, Norm
