This comes from a promo letter that custom has on their site from Bob Tucci:
"The "B & S" Perantucci F-tuba family grew with the addition of the PT-15 and PT-16 models. These may not be familiar to some musicians, those who have the famous PT-10 and PT-12 tubas.
The PT-15 five valve and PT-16 six valve F-tubas are "B & S" Perantucci instruments in the best tradition. They have the tonal quality and exquisite workmanship that made the PT-10 and PT-12 famous. The technical differences are in the area of the leadpipe, the main tuning slide and the bell.
Both lines use the same "B & S" progressive bore valve section and body bows. The leadpipe is shorter on the PT-15 and PT-16. The reduced length is incorporated into the main tuning slide, this being slightly longer. The instrument uses a fuller bell while retaining the proven 42cm rim diameter.
The short leadpipe-longer main tuning slide has also been carried over to other "B & S" F-tuba models such as the standard-bore PT-8 five valve and PT-9 six valve instruments.
These changes result in a rounder, darker sound and increased dynamic range, more in line with the tonal concepts of modern large-bore orchestral brass sections."
