I like that green myself, it is Hunter dark green.
Don't know anything about egg baskets, but track for hay trolleys goes for around $5.00 a foot. But shipping it is a problem. Also, the people that buy track want the proper track for the trolley, and there are many types of track. Even more of a problem, for track buyers is that trolleys will run on other tracks than the proper one so your trolley may not be running on the correct track. But I would take it down and put it in your blacksmith shop.
