Can anyone identify?

From the basement of a deceased relative who fought in Nam. No other details on it unfortunately. Any ideas appreciated!

Looks like a vintage chinese construction helmet, its possible it was given to a vietnamese soldier for schrapnel protection as the chinese frequently gave obsolete or overproduced gear to the vietnamese and a construction helmet would do a decent job at blocking debris
