Looks like an individual “tropical” or “survival” canister of .30 Carbine ammo for Airdrops or Onboard Aircraft Kit during Pacific Campaign.
The orange-mustard colour paint makes me think Survival equipment on large aircraft.

The Use of “sealed spamcans” of US ammo ( various sizes) began in late WW II in the Pacific, and was continued till well after the Vietnam War, for tropical use.
