I am also saddened by your story, life is sometimes cruel and indescriminate, but I know things can always get better and situations can improve! I truly hope things work out for you. I am sure whoever buys this from you will appreciate and care for it.
I know you requested to make an offer in you post, but is there a range you are looking to get? I want to be respectful of the piece's sentimental value while still taking into account what it will take to restore to full working order which I think is the only fitting course for the next stage of the system's journey.
