I have absolutely no knowledge about horns. The price has been set with reference to the sales history of the same product. As you can see in the images, there were some rust-like stains in various places. The operation was that the green circular pedal did not move. How about someone who can maintain it? Of course, if there are any defects, we will accept returns. Below is the information I have researched. This is a Marcato horn, an original from Shimokura Gakki. (I don't think it's currently sold...) The detailed craftsmanship and finish are clearly inferior to manufacturers like Yamaha, but (the bell is not thinly made, so it is heavier than instruments like Alex) ) In terms of pitch, resonance, and tone, it is a horn that cannot be underestimated, even if it is made in Taiwan (this is just a personal opinion).
