When were the American made trumpets made?

American-made trumpets began to gain prominence in the 19th century, particularly with the establishment of companies like C.G. Conn and Buescher in the late 1800s. These manufacturers played a significant role in developing high-quality brass instruments. By the early 20th century, American trumpets became widely recognized for their craftsmanship and innovation, leading to a golden age of Trumpet manufacturing in the U.S. that continues to influence instrument design today.
