Hi Tim. The only time I compared a new PT with an old one was on my cimbasso. I was using an old #9 but subsequently purchased the new version of the #9, the PT 64. On my face, they felt identical, but the bone section in the Canadian Opera Orch. felt they could hear me better with the PT 64, so perhaps there is more core or projection to the sound. Here's what that catalogue says:
"The year 1990 saw two major changes to the Perantucci tuba mouthpiece line. A new numbering system was introduced based on progressive cup volume and separation into two general cup style categories [American funnel & German bowl]. A new outside shape was given to all Perantucci mouthpieces. This is a heavy-duty version of a beloved classic design. The rims have the weight necessary for strong tone production, and the wall thickness is carefully adjusted to the volume of the respective cups."
