Looking for info on strange ammo box

[Guruman]

Back in the day, circa, 2000, my local military surplus store had bunch of white metal ammo boxes with feet on each side for bolting it down.

I bought several over the years to use on various vehicles as they were perfect for bolting to the front bumper of a Jeep for storing chains, shackles and straps.

I was told they came from the interior of a tank or armored vehicle of some kind.

I have not seen any in years, and no web search seems to even conjure a picture of one.

Anyone know what these came from or how to locate any more? Here's a pic of one painted to match the Jeep I had at the time.

Is there a part # or NSN anyplace on the box?

Unknown. I have not seen one in twenty years, and since I cannot find any other pictures or info on them, I'm kind of stuck.

I was king of hoping someone who has been around tanks or armored vehicles would recognize it. I knew it was a long shot.

In searching last night, I seem to recall that it might have been for .30 cal rounds for a machine gun, possibly linked or belt fed rounds, but the guy at the Army/Navy store might have been just making things up.

It looks like the right size to hold belt feed ammo.....now I am curious and will be searching as well
