Acetylene car located at the Queen mine
One side would fit oxygen the other side fits acetylene , then the bottles would be securely chained to the car. The gauges, tips, parts, etc. would be transported inside the box. The cars were built in Bisbee at the mine shops and used until underground operations ended.
