Freddie Mercury's piano for sale

My colleague and I are in the property business and we bought a piano from the Late Freddie Mercury's Family. The piano has been kept for a long time in a house in the Feltham Area. Apparently Freddie used to play on this when he began touring. I have verification by way of a provenance letter from Freddie's mother clearly stating the history.Wood colour with a seat. It does need tuning however I think. Freddie Mercury (born Farrokh Bulsara; 5 September 1946 – 24 November 1991) was a British rock musician and songwriter, best known as the lead singer of the rock band Queen. He is remembered for his vocal abilities and charisma as a live performer. As a songwriter, he composed many international hits, including "Killer Queen", "Bohemian Rhapsody", "Somebody to Love", "We Are the Champions" and "Crazy Little Thing Called Love." Source
