Wangyal:
LC likely has a version published in the 1930s but it would not be cataloged.
Are you interested in the map, the National Railway Publications Company, or anything else?
I will not be in the office until Tuesday October 15 to check. If this is for a patron please feel free to have them contact me directly - [log in to unmask]
