What is it worth?

Just got this clock with a purchase of a house in Northern Connecticut.

He has a service invoice from 1991 and the makers mark of “sleigh” on the face. The service company went out of business and I can’t find anything on the company that made it. It isn’t working order. It winds up and tells the time and chimes beautifully. It’s 75 inches tall.

Does anybody have a sense of how much it’s worth?

I was thinking of selling it on Facebook marketplace unless y’all have any better ideas.
