I'm sorry if this is slightly off the original topic, but I wanted to share that I totally get it. You are very lucky that you got a real piano. Have you checked the brand and the year made by its serial number? Do you know a bit of its history maybe?
I recently had to part with my piano and it was so heart wrenching; I kept crying every time I thought it was not worth repairing it and that no one would take it. It would have to end its life in the garbage. I found it 20 years ago, for free in a piano mover's basement, waiting to be destroyed like garbage. That day, I tried all the pianos there, but that one... its sound was so rich and its keyboard was not damaged. I never sought to find out what it was, I knew nothing of pianos. I just liked it.
Recently, I called a professional to tune it and repair 4 clicking keys. The unfortunate news was that it was at its end of life, and not worth repairing. What I also learned was that piano, a Knabe built in 1908 used to be the Mercedes of pianos at the time!!! A 120 years old, handcrafted with hardwood from trees grown right here, ivory keys.
