Bach trombone, 42G trombone with case. I have confirmed with the trade source that this is a: 42B GB Red bell with F-attachment. - Serial number on the slide: 83715 - Accessories: Case This is a Bach trombone with a red bell. It seems to have some rarity, but it's about 30 years old, so there are many areas with peeling and discoloration. There appears to be a repair mark on the right side of the bell in the 7th photo. I am the second owner, and I am not a trombone specialist, so I cannot make a perfect judgment. When I play it now, the sound comes out properly from top to bottom, and the tuning slide is smooth. The slide falls straight down when I let go, but I don't know if it's extremely smooth during performance (as I haven't played other trombones). Therefore, please make your judgment based on the photos, and do not purchase if you have any doubts. Please ask any questions you may have, and I will do my best to answer them in detail. The case has some tears in the leather, but it's not falling apart and should still function. When I was young, I played the euphonium, so I occasionally played the trombone in the band or when extra hands were needed. To avoid any problems, please contact me before purchasing if possible. A soft case is also planned to be sold separately. Thank you for looking.
