I purchased this in the spring of 2023 and used it for about two years, until last month, on a Hirsbrunner York model. I am taking a break from playing for a while, so I am putting it up for sale. It's difficult to see in the photos, but the tip of the shank is slightly warped. It's not enough to require repair, and it didn't affect use, but please refrain from purchasing if you are concerned. There is no box, but I will ship it in a TUBAMANPlus case. The following is quoted from the sales site: --- Based on the Helleberg II, this was produced under the supervision of Yasuhito Sugiyama, principal tuba player of the Cleveland Orchestra. To accommodate modern performance scenarios, the cup and throat have been enlarged. The response and handling have been adjusted by emphasizing the flat rim and changing the weight balance. For B♭/C tuba Rim inner diameter: 33.27mm Throat diameter: 8.204mm Cup: Deep V-cup Shank: Standard (Universal)
