Wellington Piano

Hello,
 
I have a Wellington Piano, Serial # 141530. It’s an upright, 55” tall. One of the white keys is missing its ivory and about half the keys are chipped. And someone had painted over the entire piano, so it need refinishing. I’d like to sell it. Could you tell me how old it is, and a rough estimate of its value? And where I might sell it (on-line? piano store? Antique store?)
 
Thank You,
