Antique German Piano very rare

Beautiful Antique 1870 German piano from C. Lock Ingen Berlin (not Heintzman). This piano is very rare. After researching, I cannot find one other piano of this brand for sale online. I could only find one similar German piano listed for $20,000 online. There is not much information on this piano because the company was bought out by another company in the late 1800's and that was said to have possibly burned down in the war. The piano has ivory keys and wood looks to be made of either Maple or Walnut Burl which is also a rare wood. The piano has original swinging candlestick holders and is in overall very good condition, especially for it's age. It does need to be tuned. This piano would be gorgeous fully restored or even as is. I love this piano sitting in my foyer as is. Asking $10,000. obo
