Re: [EXTERNAL] RE: Chicago-Cleveland Viking All-Steel Car Roof (UNCLASSIFIED)


Earliest examples of the Viking Corrugated Roof that I know of were built in 1934, and I've seen drawings of it dated 1933. The Climax Radial Roof dates back to at least 1924, and I would suppose the Viking All-Steel Roof was of similar vintage.
