Folks, While looking over the 1600-series Russian Decapod photographs at the Springfield-Greene County Library, I was intrigued by this photograph taken in Ft. Smith, AR in 1948. Observe the odd rolling stock on the left side. http://198.209.8.207/lochist/frisco/friscoline/images/photos/p01420.jpg The only number I can make out is "...722". Based on the siding my guess would be a caboose or company service car. The placement of the windows is quite odd placement of windows. Any clues?
I think it is a caboose because some of the Frisco wood cabooses have high windows such as the SLSF 1160 in Fort Smith, AR but many have the top windows boarded up.
