Thank you for viewing. Bach 180ML37/25 Serial: 210,000s This is from a well-made era. I acquired it used, but it seems to have been used lightly, as the pistons have good airtightness. A magnet sticks to the bell, so it has a steel wire in it. · The mouthpiece pipe has a crack. · The 3rd slide spit valve doesn't come out. · There are repair marks on the bell. Otherwise, it's as expected for its age. I considered repairing the mouthpiece pipe and using it, but I've decided to declutter since it's a good opportunity.
