Photo: Livestock Cars With Roof Hatches

A 1910 photo from the Wisconsin Historical Society:

https://www.wisconsinhistory.org/Records/Image/IM24356

The photo shows a string of livestock cars with roof hatches.

The hatches may have been for the loading of bulk commodities or, given the date of the photo, the loading of feed and water into livestock cars of an early design.

Does anyone recognize this particular car design from just the roof hatch detail?

Thanks.
