What was mounted on my FIREWALL?

I'm not aware of any bullets that grind the inside lip off after they make impact. I understand they are NOT original but if the accessory is cool enough I want to locate one and install. The idea of a tool box or OIL/WATER/GAS cans is intriguing enough for me to persue a plausible answer

By the impact and various size of the holes and jagged edge, I would say someone saw that triangle formed by the 3 ribs and thought that would make a nice bullseye. Later someone put the car back in use and ground the flare off the rear and filled the holes with body putty. Just a wild guess.
