My family has this upright Gaveau piano which was manufactured in 1906-1910 based on the serial code written inside. Although, it is upright, this Gaveau is so heavy that when we moved our house, 8 men could carry that. My father, who is a classical music historian told me that when he makes the chord of it, it last for at least 1 year. They are now planning to move but they realized that they can't bring the piano with themselves; so they have decided to sell it. By the way, we live in Turkey, Ankara. The question i want to ask is if you know somebody or some auctionary who can buy this piano and the estimated cost of it.

P.S. Here, nobody got interested; maybe i couldn't find the right people.
