Obviously the outside is not very good condition but it looks nice, despite being half finished.
Operator Piano company started in 1909. Presumably named after Scott Joplins composition, The Operator, so you would imagine the action to be relatively modern.
Most important is what is inside, and the condition of the hammers, action, is the player mechanism still there. Photos of the inside are invaluable at this point.
My guess is most technicians should say it is not worth their time repairing. The others will likely try to rip you off with a restoration costing more than the piano is finally worth.
Lots of people buy pianos like this to restore as a hobby. Very desirable, depending on how complete it is.
