As the C&S all but collapsed financially in 1910, the railroad was forced to sell an oversupply of rolling stock, particularly wood framed gondolas built in 1898 and 1902. i know many of the 1902 cars were surplussed, identical to #4319, the lone C&S Gondola of any kind to have survived which is now at Como. if the NCO had a number of wood framed gondolas, see if there isn't a strong resemblance to the #4319.
