"These are pretty rare to find," said Allen Bone, vice president of the San Bernardino Historical and Pioneer Society.
Museum officials who also serve as curators were restoring it, washing it and polishing it with utmost tender loving care on Tuesday before putting it on display.
The museum, located at the restored Santa Fe Depot, highlights San Bernardino's historic role as a railroad center.
The museum is open Saturdays 10 a.m. - 3 p.m., and it's free of charge.
