Question mark because I’m not sure.  They could also be from the very early postwar era.  These are just south of that big supply depot I posted on last weekend

The large plant just south of Kemper Road looks like it might be war-era, with the clerestory windows and central steam plant, barely visible in the birdseye

 

 

Series of plants along Cin-Day Road, not sure if all of them survive. 

 

 

Two that might.  One looks a bit like the Battleship Building in Columbus; early metal building with steel sash, and moderne head-shed

 

 

 

 

I guess this represents the extension of the Mill Creek Valley industrial zone north of the Lockland/Reading area (though I think there were some 19th century  paper factories further north along the canal in the Port Union/Rialto area

 

 

    According to the Hamilton County Auditor, larger building farthest east near Kemper Road was built in 1945 and originally owned by The Auto-Lite Company which made auto parts such as spark plugs and oil filters. A quick search of The Auto-Lite Company indicated that it supplied parts to the Army and Navy and was sold to Ford in 1961. The building was sold to the Frank Tea and Spice Co. in 1965.

 

    The one on Kemper Road farther west was built in 1953 and has been an industry related to steel since 1957. 

 

    The third one was built about 1954 and occupied by the River Raisen Paper Company until 1982.
