This model appears to be sold in North America due to trademark issues. Basically, it seems to be the same as the Perantucci model with the same number. I'm selling a PT-82 I obtained at a low price. PT-82 Cup Characteristics: Diameter 32.5mm, medium depth. Rim Characteristics: Width 8.0mm, inner rim is quite angular. Throat Bore: 8.2mm The PT82 model is a German-style mouthpiece that produces a clear, deep sound across the entire range, and its sharp inner rim provides a quick response. It's a versatile and popular model designed for CC and BB♭ tubas. (* From 2005, the old PT-83 became the current PT-82)
