While not definitive proof, please compare it to this viola sold at a German stringed instrument workshop: https://www.corilon.com/us/violas/neuner-hornsteiner-viola Please refer to the golden varnish, wood selection, etc. This is a viola made by Neuner & Hornsteiner, a manufacturer that made instruments in Mittenwald from the late 1800s to the mid-1900s. At 41.8cm, it's a bit large, but it's a size that anyone who has played the viola before can easily switch to. The model is Stradivarius type. It's a 130-year-old instrument, but there are no cracks. Bushing work has been done. There is no distortion of the arch. Please note that there are minor scratches due to being 130 years old. The strings are Evah Pirazzi Gold. Fully adjusted at a workshop in Tokyo. (Ready to play immediately upon delivery) Only the instrument and case will be shipped. I am selling it because I no longer play. It is a personal item. This instrument has been used with care for many years, so I hope to pass it on to someone who will cherish it. Feel free to ask any questions.
