Bach Cornet, CR310 I believe this is a rare model. Repairs have been made to correct some distortions. The finger hook on the 3rd slide is screw-on. The slide tubes may have been replaced with those from another of the same product. The pistons and slides are generally in good working order. As there was no original case, I will ship it in a trumpet soft case, although it's a bit snug. Please refrain from purchasing if you are overly concerned about the condition, as this is a used item. Please review the above details and images before making a purchase.
