After years of storage, no. 7101 was restored in 1936 at the Ōmiya factory (now the JR East Ōmiya General Rolling Stock Center). During the restoration, a pair of railway enthusiasts examined the engines and determined that the 7101 was originally "Benkei" (Horonai Railway no. 369) rather than "Yoshitsune" (no. 368), which had become no. 7105. Restoration was completed in 1940, and 7101, now correctly named "Benkei", was placed in the Railway Museum. There, it remained on display outside of the museum until 2007, when it was moved to the new Museum of Railway in Saitama Prefecture.
