This is a medium-bore tenor-bass trombone manufactured between the 1890s and 1980s. It is equivalent to the current YSL-640 and can be played with less air than a large-bore model, making it easy for beginners or those with less lung capacity to play. It is characterized by its light blowing feel and smooth, bright sound.
