Came across this online while searching for a steam locomotive photo:

Ron V. Nixon Collection Image Record - rvn21078
http://www.morphotoarchive.org/rvndb/rvn_date_jpeg_rec.php?objno=RVN21078

"WCLX Wilson private line Mechanical Refrigerator cars in Missoula, MT."
June 14, 1957       Location: Missoula, MT       Photographer: Ron V. Nixon
Railroad: Northern Pacific Railway       

3 cars are shown.  The original is probably a 616 (2.5x4.5) negative, so should have good detail.

Has anyone ever done a deep dive on history the Wilson fleet during the steam era?
