The tremolo harmonica was invented by Wilhelm Anton Thie a harmonica maker in the 1830s and used the german Richter tuning. The tremolo harmonica is also very popular in Asia and for instance, in Japan we use a different tuning more suited to traditional folk music created by Shōgo Kawaguchi (川口章吾).
The tremolo harmonica is sometimes referred to as grandpa's harmonica since it was this old-style harmonica that was so popular in the 19th century. This harmonica is unfortunately very limited in the sense that you can only blow and draw notes and the note layout let you only play very simple diatonic melodies.
Another specificity of the tremolo harmonica is its sound. Each note is produced by two reeds vibrating simultaneously. While one reed is tuned a bit low the other one is tuned a bit higher creating a modulation effect called tremolo. When you blow or draw a note the sound you hear is two reeds playing at the same time with a moving effect very similar to the sound of an accordion. The tremolo is still popular today because it doesn't require as much technique as the diatonic or chromatic harmonicas and can easily play simple melodies. The downside being that it is fairly limited.
Most brands offer at least one tremolo model.
