This is a professional Bb trumpet made in Elkart, Indiana, USA. This Bach LR180S37 is part of Bach's Stradivarius line as made since 1965.
The Bach's medium-large bore is the standard for balance of projection and resistance. The 37 bell is the most popular for symphony and band use, with a clear tone with the most projection. LR means Leadpipe Reversed. On this model the tuning slide fits over the leadpipe rather than inside it, so it makes the trumpet play a little larger and more open, but not as much as a large bore trumpet. You can tell the Bach LR trumpets by the single tuning slide brace and staggered gap when it's pulled. I removed the tuning slide in one photo to show.
I bought this trumpet from the Bach factory as used in 2020. It's nearly a new instrument actually, but has two plating blemishes on the first valve casing. And some black funk where the 1st slide comes out. You don't see them when you hold the trumpet or if you use a leather valve guard. Includes 1-year Horn Guys warranty, excluding finish, but no factory warranty.
I wiped the trumpet with a soft cloth before taking photos, but I didn't polish it. You'll see some darkening of the finish in a few photos. I'll make sure it's next level shiny before shipping.
Includes Bach hard case, 7C mouthpiece, Bach valve oil.
