Leblanc Infinite Upper and Lower Joints Slim Barrel and Traditional Bell... Cocobolo wood by Backun (old logo) This is an old item, so I will explain it in detail below. I want to sell it to someone who can purchase it with peace of mind and understanding. Please feel free to contact me if you have any questions. No returns or exchanges. The Infinite was the top-of-the-line model from Leblanc during the time it was made in France, around the 1990s. (Infinite means "infinity" in French.) According to online research, it uses high-quality grenadilla wood, which is not seen in the current American-made models, and is thickly plated in multiple layers to achieve a rich tone. I was fortunate enough to obtain only the upper and lower joints. The serial numbers match. Unfortunately, as it is old, there are some scratches on the plating in various places. There appear to be no cracks in the body. Three years ago, all the pads were replaced with leather, and it was used for about a year, after which it was stored. The barrel and bell are made of cocobolo wood. They have the Nonaka Backun logo. The barrel is 66.5mm, which is slightly longer. It is the now-discontinued slim type. The bell is stamped "prototype." It is a traditional model. Both have serial numbers starting with "S," so they may be for Selmer. However, I have had them inspected by musical instrument stores and professional musicians, and they can be attached and played without any problems.
