A local history buff in the area stated that the barn probably had a silo made by the Unadilla Silo Company. They were started in Unadilla, NY in 1909 and have produced many of the silos used across the state and the country. They are still in business and build silos. Given the vintage of the barn, I assume the silo was wooden, like the one I show below.

The silo would have been held together with metal hoops. I have not found any evidence of the silo hardware – it, like the rest of the silo, is long gone. There are still wooden silos around. I’ll have to inspect a few when I get a chance – before they are gone also!
