Ittner Etna piano number is 26764. How about this piano? In what era, can you provide as detailed information as possible, and what is the price of second-hand goods?

Ittner is the lowest piano launched by Yamaha in China. You can hardly see it on the market now. At present, the choice of flax raw materials in China is very low. What's more, Ittner is much lower than Yamaha. Personally, I think it is worthless at all, and the price is between 4000 and 5000.
