Time service! This is an interior part from a Japanese National Railways (JNR) sleeper express train car. It's a part used on trains like Akebono, Nihonkai, Hakutsuru, and Yuzuru, etc. I believe this is a very rare part. The upper bunk fall prevention handrail is also included. It's very useful when installing in a narrow space. It would be very expensive to make something like this. - Material: Aluminum - Usage: Ladder for upper bunk use - Design: Step storage structure Thank you for viewing.
