Modern equivalent would get a recorded message
Hi Jordan
Loud little video, but you can see how it would get the drivers attention even in a CMP. Modern equivalent would get a recorded message saying the driver is unavailable at this time please leave a message.
As a teenager spent several summers working in a summer camp (1960s) because of the small number of people who could drive a nonsychro manual transmission I was selected to drive the camps 1948 F5 Ford stake truck hauling 18 to 20 campers. If they wanted the driver they pounder on the cab roof. Which was similar to being inside a kettle drum.
Enjoyin your work.
Cheers Phil
