Thanks for your question. Welcome to JustAnswer, it will be my pleasure to help you. My name is***** am working on this for you now.
Is this a piano? If so is it an upright or a grand piano? What is the name of it? If it is an upright piano, what is the height from the floor to the top of the closed top lid? If it is a grand, what is the length measured from the outside edge of the wood along the front of the keys to the furthest edge of the top away from the keys over the leg.
Do you have a serial number? Has it been regularly tuned and maintained?
Have any of the internal mechanics been replaced or restored over the years or is it all still as originally built?
