The keyboard is in excellent condition. There is one broken middle D string (there are 2 strings per key in this section of the piano). The note D still sounds because there is still one string there where two should be. If I can find a replacement string locally I will install it, otherwise the purchaser will have to find the replacement string and have it installed, or install it themselves.Strings are very easy to install. I rarely broke any strings so almost all of the strings are original. All hardware, including damper pedal, AC adaptor, legs, etc. Are original and in perfect working order. The keyboard is over forty years old, never abused, and all the keys and internal parts are in immaculate shape. The serial number is 8600 (photo supplied).
