I have found a music warehouse that (might) come and pick it up. They sell it on consignment. I don't expect to get much for it. Modern digital keyboards are so much cheaper and dead easy to transport. They never need tuning. And they can even be adjusted to tune every key up or down at once to match another instrument. Much nicer, in my book. Even my mother's adopted son who is a purist, preferred his electronic piano, and he lived right next door to this upright and could have played it any time.
I think the estate sale business and trailer sales will both be strongly affected by Covid-19. Too many old folks stuff makes a glut in the market. I have three complete sets of expensive china of my mom's, and all I want is some more Corelle dinner plates. Her silverware might be worth more in melt value.
