The guys at P D Gough were critical of the way that the original pipes were welded to the front and rear of the boxes. So on the new ones, they belled the box end plates and extended the pipes a few cm into the can before welding which produces a much more robust joint. It does result in the internal oblique perforated pipe being a little shorter but this doesn't seem to have any detrimental effect.

These photos should give you a better idea of what else was done to strengthen the original design. (Sorry it's taken a while to post the photos.)
