Yamaha Flute, All Silver Professional Model YFL-611 With E mechanism C key tone holes are soldered only This is the 600 series, a lower model of the top-of-the-line handmade 800 series at the time. In terms of price, the 6 series was from 400,000 yen, and the 8 series was from 500,000 yen. It is a model similar to the discontinued YFL-711. This is the previous model of the 611Ⅱ, a beautiful engraved Japanese-made flute. Engravings are still present on the lip plate, crown, and keys, but flutes with patterns on the body tube are rarely seen even in limited editions these days. Only tube cleaning, disassembly and polishing, oiling, and balance adjustment have been performed. No key sticking or malfunctions were observed. Although it has been used for many years, it is still a fully functional instrument. There is a small dent about the size of a grain of rice near the upper trill key of the body tube (photo 4).
