Bach · Professional · 180S37 · 1960s–present (180 series)
Vincent Bach sold his first Stradivarius trumpet in 1925, and Bach Brass calls the 180 series the best-selling professional trumpet in the world. The 180 came out of the sale to Selmer in 1961. Selmer asked Bach to redesign his trumpet so it tuned with the usual half-inch pull on the main slide, and the result was dubbed the model 180. BachLoyalist's earliest known 180 dates from 1962, still in Mount Vernon, and production moved to Elkhart, Indiana, in 1964 and 1965. The Strads are still built there. The name tells you the spec. The 180 is the body, the S means silver plate and 37 is the bell, the one-piece hand-hammered bell Bach still treats as its standard. Add a 0.459-inch medium-large bore, a #25 leadpipe and Monel pistons, and Bach pitches the result for everything from jazz to concert and solo playing. Collectors argue about eras. Mount Vernon horns are still hotly sought after, and early Elkhart horns before 1977 have two-piece valve casings. Counterfeits turn up online, so check the serial and markings before anything else.
This is a professional trumpet, so it's the right buy for a serious high school player or an adult, not a first-year student. If you're buying for a teenager moving up, a used 180S37 can last them for decades.
Build and case180S37
The serial number is stamped on the second valve casing. BachLoyalist's list puts Elkhart serials at about 30,000 in 1965, 175,000 by 1980, 336,000 by 1990, 500,000 by 1999 and 700,000 in 2012. Its model table has 180s built with two-piece valve casings until 1977 and one-piece casings after.
Counterfeit Stradivarius trumpets sell online, and BachLoyalist lists their tells, from long laser-etched serials to full model numbers on the leadpipe. On real horns, check the leadpipe for red rot and the slides for dents, both shop repairs.

Buying guide
We'd buy a Strad a seller has had serviced, like the 180S37 titled chem cleaned and serviced at $1,650 delivered, a little under the $1,725–2,225 band. There are at least 118 for sale, almost all in the US, and most titles just say Model 37 (silver is the 180S37, lacquer the 18037). New ones from dealers ask about $4,095, so a used Strad in the band saves about half. Counterfeit Strads are sold online, so check the serial on the second valve casing in the photos and look at the leadpipe for pink red-rot spots. This is a pro trumpet for a serious high schooler or an adult, and we'd skip the $366 auction from a zero-feedback seller, which is far too cheap for a real one.
$1,532.79est. delivered
The lowest delivered fixed-price Strad here at $1,533, titled ML bore with the original case, which the seller calls worn. There's no service claim, so ask for the serial on the second valve casing and a valve video, and budget for a shop check-up.
