I work at a railroad museum and we have in our collection a US Army hospital car, but we're not sure where/when it was actually in service. We believe it was built in 1945, and according to conflicting info it was either used in WWII (imo doubtful due to date of construction) or the Korean War or both.
It's designated US car #89436, but our own museum website is the only result for that search term on regular google.
Hello there! As your question is related to looking for identification/information regarding military personnel, our Guide on Military Identification may be of use to you. It provides a number of different resources, including how to request service records from a number of national agencies around the world, as well as graphical aids to assist in deciphering rank, unit, and other forms of badges or insignia. While the users here may still be able to lend you more assistance, hopefully this will provide a good place to start!
